Peter Collingbourne c4d37a78cc Compute base addresses from program headers while reading /proc/self/maps. 
We previously had logic to compute the base address from program
headers as part of symbolization. The problem is that we need a correct
base address earlier in order to adjust a PC into the image's address
space, as these addresses can appear in unsymbolized output.

There was previously an assumption that only the mapping that
was lowest in the address space did not need to be adjusted. This
assumption is not guaranteed (for example, the kernel may choose to
map an ET_DYN lowest) and in fact turned out to be wrong in binaries
linked with lld because the first mapping is read-only.

The solution is to move the program header reading logic into the
code that reads /proc/self/maps.

There is a change in semantics for clients that install a callback
using the InstallSymbolizeOpenObjectFileCallback function. Any such
clients will need to return a correct base address from the callback
by reading program headers using code similar to that in the function
OpenObjectFileContainingPcAndGetStartAddress.

README 

This repository contains a C++ implementation of the Google logging
module.  Documentation for the implementation is in doc/.

See INSTALL for (generic) installation instructions for C++: basically
   ./autogen.sh && ./configure && make && make install
