Alexey Samsonov aa05110a17 [ASan] Create new files asan_report.{h,cc} as a preparation for refactoring of ASan error reporting code. 
Currently ASan reports many kinds of errors, and the code that actually prints error messages can
be found inside allocator, OS-specific files, interceptors code etc.

An example of maintenance troubles this situation causes:
There is currently an ASan interface function that registers
callback which should take the char buffer with error report printed by ASan.
This function is now broken, as one has to insert callback calls to all the places in
ASan code where the error reports are printed, surprisingly it is not only
"__asan_report_error" function...

README.txt 

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (asan) run-time library.
We are in the process of integrating AddressSanitizer with LLVM, stay tuned.

Directory structre:

README.txt       : This file.
Makefile.mk      : Currently a stub for a proper makefile. not usable.
Makefile.old     : Old out-of-tree makefile, the only usable one so far.
asan_*.{cc,h}    : Sources of the asan run-time lirbary.
mach_override/*  : Utility to override functions on Darwin (MIT License).
scripts/*        : Helper scripts.

Temporary build instructions (verified on linux):

cd lib/asan
make -f Makefile.old get_third_party  # gets googletest and cpplint
make -f Makefile.old test -j 8 CLANG_BUILD=/path/to/Release+Asserts
# Optional:
# make -f Makefile.old install # installs clang and rt to lib/asan_clang_linux
