Alexander Potapenko 0a4e0f6d35 Fix a use-after-unmap bug in /proc/self/maps caching. The cached buffer was occasionally deleted in the MemoryMappingLayout destructor.

Alexander Potapenko e2b6d08459 Use a struct to hold the /proc/self/maps buffer on Linux.

Alexander Potapenko 7811425843 Add caching to the MemoryMappingLayout class on Linux. This is necessary for the cases when a sandbox prevents ASan from reading the mappings
from /proc/self/maps.
The mappings are currently being cached on each access to /proc/self/maps. In the future we'll need to add an API that allows the client to notify ASan about the sandbox.

Kostya Serebryany 734f1eb5f4 [asan/tsan] do not use __WORDSIZE macro, as it is glibc-private thing. Instead, define our own SANITIZER_WORDSIZE

Alexey Samsonov 7acdc1738f [Sanitizer] When obtaining the data for loaded modules, add address ranges of loadable segments only. Looks like address range of PT_TLS segment may intersect with loadable segments of other modules.

Alexey Samsonov 961276af26 [Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections. To symbolize an address from a module, map this module to memory and obtain pointers to debug info sections. Later these pointers can be passed to constructor of DWARF context-in-memory from LLVM DebugInfo lib.
