Alexander Potapenko 3182c3e441 [ASan] Fix https://code.google.com/p/address-sanitizer/issues/detail?id=159 
MaybeReexec() does now a tricky job to manage DYLD_INSERT_LIBRARIES in a safe way.

Because we're using library interposition, it's critical for an instrumented app
to be executed with the runtime library present in DYLD_INSERT_LIBRARIES list.
Therefore if it's initially missing in that list, we append the runtime library name
to the value of DYLD_INSERT_LIBRARIES and then exec() ourselves.

On the other hand, some of the apps exec()ed by our program may not want to have
ASan runtime library preloaded, so we remove the runtime library from the
DYLD_INSERT_LIBRARIES if it's already there.

Users may want to preload other libraries using DYLD_INSERT_LIBRARIES, so we preserve those.

Kostya Serebryany fd61b6f0c8 [asan] make asan work with 7fff8000 offset and prelink 
When prelink is installed in the system, prelink-ed
libraries map between 0x003000000000 and 0x004000000000 thus occupying the shadow Gap,
so we need so split the address space even further, like this:
|| [0x10007fff8000, 0x7fffffffffff] || HighMem    ||
|| [0x02008fff7000, 0x10007fff7fff] || HighShadow ||
|| [0x004000000000, 0x02008fff6fff] || ShadowGap3 ||
|| [0x003000000000, 0x003fffffffff] || MidMem     ||
|| [0x00087fff8000, 0x002fffffffff] || ShadowGap2 ||
|| [0x00067fff8000, 0x00087fff7fff] || MidShadow  ||
|| [0x00008fff7000, 0x00067fff7fff] || ShadowGap  ||
|| [0x00007fff8000, 0x00008fff6fff] || LowShadow  ||
|| [0x000000000000, 0x00007fff7fff] || LowMem     ||

Do it only if necessary.

Also added a bit of profiling code to make sure that the
mapping code is efficient.

Added a lit test to simulate prelink-ed libraries.
Unfortunately, this test does not work with binutils-gold linker.
If gold is the default linker the test silently passes.

Also replaced
__has_feature(address_sanitizer)
with
__has_feature(address_sanitizer) || defined(__SANITIZE_ADDRESS__)
in two places.

Patch partially by Jakub Jelinek.

Evgeniy Stepanov 87c43537df [sanitizer] Improve scanf interceptor 
This a rewrite of the scanf parser. The new implementation is pretty close to
the spec, with a few shortcuts taken here and there. It is conservative, i.e.
it gives up parsing if it does not understand some part of the format string,
or runs into an ambiguous % spec. It does not handle some rarely used parts of
the spec, like %n$ - for now.

I'm also moving parser call to after the original *scanf function completes,
so that we can find out the store size of %s directive by the use of strlen()
on the target buffer.

Alexander Potapenko cae42d23a6 [ASan] Use dylib interposition to hook memory allocation in the dynamic runtime. 
This CL drastically simplifies the way we're hooking the memory allocation routines in ASan on Mac by using dylib interposition to replace the main malloc_zone_* functions. This allows us to avoid replacing the default CFAllocator and drop the CF dependency at all.

Committing this patch will result in the static runtime being broken. A follow-up CL will switch ASan to use the dynamic runtime library.

Jakob Stoklund Olesen 7956e0094d Revert r172719, r172721-172723, and r172725. 
The r172719 patch broke the build on Mac, the others depended on it.

Peter Collingbourne 6600516a58 Have ReExec read environment from /proc/self/environ 
It is possible for ReExec to be called before the C standard library
has initialised itself sufficiently for execv to work properly.
Fix this by parsing the environment ourselves and using execve.

Kostya Serebryany 35cc75876a [asan] asan_allocator2: implement adaptive redzones. Now with asan_allocator2 allocations <= 48 bytes have 16 byte redzone, allocations of 48-96 bytes -- have 32 bytes redzone, etc (max redzone is 2048). If ASAN_OPTIONS=redzone=n is set, it changes the minimal redzone size
