packaging: append -ldl -lpthread to ASan force options.

When building for address sanitization, some packages complain about
missing symbols due to omitted -ldl or -pthread.  This patch appends
-ldl and -lpthread to the ASan force options in order to resolve this
kind of issue.  Note that since -ldl and -lpthread are already needed
by libasan, adding them to the ASan force options should not cause any
problems.

This patch also adds -Wl,--as-needed before -ldl -lpthread in the
force options to prevent libdl or libpthread from being linked when
unnecessary.

packaging: create a wrapper for collect2 in gcc-force-options

gcc-force-options used to prepend/append all force options to the
gcc/g++ wrappers.  This approach worked well for most packages but
caused some configure scripts to behave differently when linker flags
are included in the force options.  For example, if g++ is called with
-ldl appended, it always goes to the linking phase.  As a result, when
configure has expanded AC_PROG_CXXCPP macro, variables related to
preprocessor are not properly set and actual build ends up using
incorrect compile and link flags.

Since prepending or appending linker flags to the linker makes more
sense than carrying them from the compilation phase, this patch
basically divides the force options into compiler flags and linker
ones, and inserts them to corresponding wrappers.  Consequently, a
wrapper for collect2 is created, as we did for gcc and g++, in order
to pass the linker flags to the linker.  Note that collect2 bridges
the compiler and the actual linker, and thus creating a wrapper for
collect2 is more portable and succinct than doing so for linkers.

    [asan/lsan] Avoid possible deadlock in dynamic ASan runtime thread initialization.

    There is possible deadlock in dynamic ASan runtime when we dlopen() shared lib
    which creates a thread at the global initialization stage. The scenario:

    1) dlopen grabs a GI_pthread_mutex_lock in main thread.
    2) main thread calls pthread_create, ASan intercepts it, calls real pthread_create
       and waits for the second thread to be "fully initialized".
    3) Newly created thread tries to access a thread local disable_counter in LSan
       (to complete its "full initialization") and hangs in tls_get_addr_tail, because
       it also tries to acquire GI_pthread_mutex_lock.

     The issue is reproducible on relative recent Glibc versions e.g. 2.23.

Make lsan-force-options and lsan-build-env more usable. Factor out common
code from {A, UB}San to sanitizer_common code.

Add -fno-omit-frame-pointer -U_FORTIFY_SOURCE to lsan-force-options because
LSan heavily relies on frame pointers. Disable LSan in QEMU builds through
LSAN_OPTIONS file. Refactor Tizen specific patches in ASan and UBSan.

Fix ASan tests.

Some ASan tests fail due to:
1) Unable to unwind malloc trace.
2) Return invalid code due to hant_on_error=false enabled by default.

Let's fix this.

Set detect_leaks and halt_on_error to false by default because mic

It seems that we have lots of redundant MaybeMountProcFS, in particular
each mapped sanitized shared library calls it from AsanInitializer constructor.
Remove redudant MaybeMountProcFS calls from AsanInitializer and __asan_init.

Also, it seems that under qemu-aarch64 opening /proc/self/maps for reading

FileExists("/proc/self/maps") in MaybeMountProcFS to avoid expensive calls.

Add mmap/munmap interceptors.

Some allocators may use mmap for their local pools that may cause false positive
reports because LSan currently doesn't intercept mmap call mainly due to its
complexity (we don't know whether a particular mmap would contain live pointers).
However for some cases (e.g. anonymous rw mmaps) we can guess that they would
contain live pointers thus we can add them into root regions. Thus, now we
intercept mmap/munmap calls, add anonymous rw mappings into root regions and
call real mmap.
