6e5a113837 a bit more -Werror compatability
for clang, fix warnings in drivers/, lib/, servers/, sys/, common/.
by turning off fatal warnings (takes effect if the default is on),
fixing warnings or reducing the warning level.

fbd82e76a4 Let the build system manage compilation flags
Do not hardcode warning and optimisation flags, otherwise the
main options (i.e. DBG, CPPFLAGS) will not work as expected.

You can still provide specific default by using DBG?=<value>.

Doing so leaves the opportunity to override the setting from the
commandline, while the default value from the build system is
then ignored for that particular package.

When crosscompiling, and using build.sh, adding -V DBG=<value> has
this same effect as make DBG=<value>.

e415d48872 Libc update to simplify merge.
Bumping libc files for unsupported architectures, to simplify merging.
A bunch of small fixes:
 * in libutil update
 * the macro in endian.h
 * some undefined types due to clear separation from host.
 * Fix a warning for cdbr.c

Some modification which were required for the new build system:
 * inclusion path for const.h in sconst, still hacky
 * Removed default malloc.c which conflicts on some occasions.

76092ddf33 libmthread: don't always verify library initialization
This can be turned back on when the library is compiled with
-DMTHREAD_STRICT (which enables more sanity checks). However,
always performing this check shows up in system profiling results.

accaae9b2c libmthread: add guard pages to stacks
Add guard pages to the top of the stack to catch overflow errors.
Moreover, fix a bug where libmthread would keep using a stack that was
just deallocated; a detached thread would deallocate its own stack after
it was finished running).

c8d0edc06a - Refactor mthread structure fields to prevent name clashes
- Remove sanity checks for initialized mutexes and condition variables. This
  significantly boosts performance. The checks can be turned back on by
  compiling libmthread with MTHREAD_STRICT. According to POSIX operations on
  uninitialized variables are a MAY fail if, therefore allowing this
  optimization.
- Test59 has to be accommodated to the lack of sanity checks on uninitialized
  variables in the library. It specifically tests for them and will run into
  segfaults when the checks are absent in the library.
- Fix a few bugs related to the scheduler
- Do some general code cleanups

a7072a5e1c Revamp the mthread library and update test59
Before, the 'main thread' of a process was never taken into account anywhere in
the library, causing mutexes not to work properly (and consequently, neither
did the condition variables). For example, if the 'main thread' (that is, the
thread which is started at the beginning of a process; not a spawned thread by
the library) would lock a mutex, it wasn't actually locked.
