3afc8f0a3f Fix process_munmap not handling munmap correctly. 
munmap(2) will unmap any page "it touches", the parameters
given to it do not necessarily need to match the ones given to mmap(2).
It is legit to specify pages that are not mapped at all, ranges that
span multiple mappings, with or without holes…

Beside that, a logic error in calculating the size for
process_release_mem() is fixed in the case a munmap would split
a previous allocation in two maps.

Similar fix also for the case where the freed page is at the end
of the allocated area.

be3b4c22ae Fix logic error in process_rb_search_range() 
The function would not properly check if addr is within the block
due to inversed logic in the comparasion.

871a79f35b mremap handling in case of error and creating a duplicate mapping. 
- mremap can fail, in this case the old mapping is retained.
- mremap, when oldsize is 0, a new mapping is created without freeing
the old one.

See mremap(2) for details.

f090e95e83 munmap can fail. 
According to munmap(2), the call can fail, e.g if the adress given is
not at a page boundary.

61a32cf95e Consider page size in report_mmap / report_unmap. 
mmaps are full of quirks ;-)

- mmap(2) will always allocate whole memory pages, even if the
  caller only reuqests a partial page.
  This is considered by calculating the "real" size of the mmap.

- munmap(2) also operates on pages, unmapping every page it "touches.",
  so the size parameter is adjusted if needed.

ce552acad2 find_library(liberty) will also take care of the demangle header 
so, CHECK_INCLUDE_FILES_ERROR(libiberty/demangle.h) is not needed and
actually fails to find the header if the header is in some non-standard
location. (e.g if it comes from a conan package)

7d8fb9ec75 Wimplicit_fallthrough requires gcc7 or newer, so only enable it there. 
Also disable -Werror, as this is a great annoyance and breaks the build
with (newer) gccs or when some hardening options are enabled.

5f0dd75c1f Use rl_clear_history only if available, fallback to clear_history if not. 
For ancient readline (I'm stuck to it on my embedded target...),
rl_clear_history is not available, so using clear_history instead.
