Fix etl::chrono floor/ceil/round/abs being declared in the wrong namespace
The duration overloads of floor, ceil, round and abs were defined in
namespace etl rather than etl::chrono, so qualified calls such as
etl::chrono::floor<seconds>(ms) only found the time_point overload and
failed to compile. Moved them into namespace chrono next to
duration_cast and removed the old etl-scope definitions, which also
fixes the unqualified calls made from time_point.h.
Fix comment about rounding behavior
Use cmath functions from std namespace
GCC 16 doesn't support them in the global namespace anymore.

* Help the compiler optimize unaligned_type.
This fixes a regression in 266b0f99 when the type was made constexpr. When
switching to a loop to construct the value the compiler was unable to detect
what was going on. We now unroll the loop at compile time into what's
essentially a hand rolled shift and OR operation which the compiler detects
and replaces with a byte swap. Tested on gcc (x86+arm) and clang (x86).
Introduce a static value_from which can be used to convert a value from an
existing buffer. There were previously three options for this, all bad or
awkward in different ways:
- val = etl::be_uint32_t(address)
Copies to temporary storage.
- val = *reinterpret_cast<const etl::be_uint32_t*>(address);
Unreadable.
- etl::be_uint32_t::copy_store_to_value(address, output);
Requires an output parameter.
The new addition is:
- val = etl::be_uint32_t::value_from(address);
Additionally, update the documentation with value_from and the missing,
existing constructors.
* Please clang-format.

* Adopt the Library Fundamentals TS make_array design for the sequence factories
make_array, make_deque, make_vector, make_list, make_forward_list and
make_indirect_vector now follow the Library Fundamentals TS
std::experimental::make_array design: a defaulted leading template
parameter selects the element type explicitly, falling back to the
decayed common type of the arguments when it is not supplied. A shared
trait (etl::private_make::element_type) performs the selection lazily,
so common_type is not instantiated when the element type is explicit.
This fixes the explicit-element-type calling style for the four
common-type factories, where make_vector<char>(lvalue) never compiled:
the explicit argument pinned the first pack parameter to char, making
it a char&& that no lvalue can bind to. It also gives make_array and
make_deque the deduced form (e.g. make_array(1, 2L) is array<long, 2>)
for free. All arguments are converted with static_cast, as in the
make_array const-lvalue fix, so const-qualified lvalues and narrowing
initialisers work in both forms.
Intentional behaviour change: an explicit element type now converts
every argument instead of pinning only the first. make_vector<char>(0,
1, ...) previously produced vector<int> - the explicit char affected
only the first argument and the element type was still the common type
- and now produces vector<char>. test_make_vector documented the old
behaviour and has been updated.
The keyed set and map factories are unchanged: their key/mapped types
are separate mandatory template parameters ahead of a fully-deduced
pack, so the explicit-type style already works, and retrofitting
deduction there would interact with the defaulted comparator/hash
parameters.
Adds explicit-element-type tests for the four common-type factories
(const/non-const lvalues plus narrowing initialisers) and
deduced-element-type tests for make_array and make_deque, and updates
the four documented signatures.
* Address review comments on the make_xxx factory design
- Forward same-type arguments in the make_xxx factories instead of
casting them. static_cast produced a prvalue that, before C++17, had
to be materialised through the move constructor, rejecting
copyable-but-non-movable element types. The new
private_make::convert helper forwards arguments that already have
the element type and static_casts the rest.
- Drop ETL_NOEXCEPT from make_array: conversions can throw, and the
other factories do not declare it.
- Remove the redundant etl::decay in element_type<void, ...>;
etl::common_type already decays its arguments.
- Stop leaking the etl::private_make implementation namespace into the
documented factory signatures.
* Add a test for make_array with an explicit element type and no arguments
etl::make_array<int>() produces an empty etl::array<int, 0> and now has
a regression test. A call with neither an element type nor arguments
remains ill-formed, matching the Library Fundamentals TS: there is
nothing to deduce the element type from. The array documentation now
states this explicitly.

* Corrected the documented make_xxx factory signatures and examples
The Make template sections across the container documentation had
drifted from the implementations, largely through copy-paste:
- map.md, multimap.md and flat-multimap.md all documented
make_flat_map; multiset.md documented make_set; flat-multiset.md
documented make_flat_set; unordered-multimap.md documented
make_unordered_map. Names and examples now match each container.
- Every signature omitted the C++11-required trailing return type
despite the sections being labelled C++11 and above; several also
used a parameter name (TValues) that did not match any template
parameter, and the unordered map headers were missing a comma.
- forward-list.md documented a make_array-style signature with an
explicit element type; the real function deduces the element type as
the common type of the arguments, as documented for make_list.
- The flat_set/flat_multiset template headers were missing the
variadic parameter pack, and their examples passed a braced list to
a variadic function, which does not compile; set.md used TKeyCompare
where the implementation uses TCompare.
- deque.md and the reference container docs were missing code fences.
- Updated the four reference_flat_* function. However these functions
cannot be instantiated at all (the reference containers have no
initializer_list constructor, since one would dangle by design), so
the documented examples have never compiled.
Every remaining documented example verified to compile with clang 22
(C++17) against the current headers.
* Fixed C++17-only syntax in factory examples and flagged the non-compilable ones
Review feedback on the make_xxx documentation examples:
- All the map-family factory examples are labelled C++11 and above but
constructed their pairs with class template argument deduction
(etl::pair{0, 1}), which requires C++17. The pairs in the make_flat_map,
make_flat_multimap, make_map, make_multimap, make_unordered_map,
make_unordered_multimap, make_reference_flat_map and
make_reference_flat_multimap examples now name their template arguments
explicitly. The template deduction guide examples are unchanged, as
those sections are labelled C++17 and above. Verified with clang 22 in
C++14 mode, which, like C++11, has no deduction guides.
- The four make_reference_flat_* examples are now preceded by a warning
callout stating that they do not currently compile: the functions
cannot be instantiated because the reference containers have no
initializer_list constructor. The examples themselves are retained,
rewritten to pass named lvalues rather than temporaries, since the
reference containers store references to external objects and the
temporaries would dangle even if the functions compiled. The defect
is being reported separately.

make_list was the only make_xxx container factory taking its argument
pack by value rather than by forwarding reference, costing an extra
move per lvalue argument: each lvalue was copy-constructed into the
parameter and then moved into the initializer_list backing array,
where the forwarding-reference signature copies it there directly.
Rvalue prvalue arguments count the same either way in practice, as
copy elision constructs them directly into the by-value parameter.
Change the pack to T&&..., matching make_vector, make_forward_list and
make_indirect_vector. The deduced reference types decay through
common_type, so the element type deduction is unchanged.
Adds tests for const/non-const lvalues of the element type (guarding
against the forward<T> defect fixed for make_array and make_deque),
mixed-type common_type deduction, and an instrumented type counting
copy/move constructions, which fails with the by-value signature (one
extra move per lvalue argument) and passes with the fix.
Also corrects the make_list documentation, which described a
make_array-style signature with an explicit element type parameter
that never matched the implementation.
Verified with clang 22 (C++17): all 93 list tests pass; C++14/20
syntax checks pass.
Note: mixed-type lvalue arguments are affected by a separate
pre-existing defect in etl::common_type (its two-type specialization
recurses with decay<T2> twice instead of decay<T1>, decay<T2>), which
already affects the other common_type-based factories and is being
fixed separately.
