Ian Barkley-Yeung f5123d7196 Add #include <config.h> to the beginning of all cc files 
Added
 #ifdef HAVE_CONFIG_H
 #include <config.h>
 #endif
to the beginning of all source files that didn't have it.

This ensures that configuration options are respected in all source
files. In particular, it ensures that the defines needed to fix Large
File System issues are set before including system headers.

More generally, it ensures consistency between the source files, and
avoids the possibility of ODR violations between source files that were
including config.h and source files that were not.

Process:
Ran
find . \( -name third_party -prune \) -o \( -name '.git*' -prune \) -o \( \( -name '*.cc' -o -name '*.c' \) -exec sed -i '0,/^#include/ s/^#include/#ifdef HAVE_CONFIG_H\n#include <config.h>  \/\/ Must come first\n#endif\n\n#include/' {} + \)
and then manually fixed up src/common/linux/guid_creator.cc,
src/tools/solaris/dump_syms/testdata/dump_syms_regtest.cc,
src/tools/windows/dump_syms/testdata/dump_syms_regtest.cc,
src/common/stabs_reader.h, and src/common/linux/breakpad_getcontext.h.

BUG=google-breakpad:877
Fixed: google-breakpad:877
TEST=./configure && make && make check
TEST=Did the find/sed in ChromeOS's copy, ensured emerge-hana google-breakpad
worked and had fewer LFS violations.
TEST=Did the find/sed in Chrome's copy, ensured compiling hana, windows, linux, and
eve still worked (since Chrome doesn't used config.h)

// fast_source_line_resolver_unittest.cc: Unit tests for FastSourceLineResolver.
// Two different approaches for testing fast source line resolver:
// First, use the same unit test data for basic source line resolver.
// Second, read data from symbol files, load them as basic modules, and then
// serialize them and load the serialized data as fast modules. Then compare
// modules to assure the fast module contains exactly the same data as
// basic module.
