This patch is taken from the downstream version of breakpad in
Chromium OS: https://gerrit.chromium.org/gerrit/15148
LinuxCoreDumperTest previously assumes the proc files of the child
process created by CrashGenerator::CreateChildCrash() have the same
content as its parent process, which may not be true. This CL modifies
CrashGenerator to copy the proc files of the child process, created by
CreateChildCrash(), before crashing that process.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Turn the LinuxDumper class into a base class and move ptrace related
code into a new derived class, LinuxPtraceDumper.
2. Add a LinuxCoreDumper class, which is derived from LinuxDumper, to
extract information from a crashed process via a core dump file instead
of ptrace.
3. Add a WriteMinidumpFromCore function to
src/client/linux/minidump_writer/minidump_writer.h,
which uses LinuxCoreDumper to extract information from a core dump file.
4. Add a core2md utility, which simply wraps WriteMinidumpFromCore, for
converting a core dump to a minidump.

2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock).
3. All unit tests pass.
4. Run Chromium OS tests to test core2md.

CrashGenerator::CreateChildCrash() may have some flakiness. This patch
changes ElfCoreDumpTest to temporarily skip the ValidCoreFile test if
no core dump is generated by CrashGenerator::CreateChildCrash(), but
print out the error message to help debug the flakiness.

This patch is part of a bigger patch that helps merging the breakpad code

Specifically, this patch makes the following changes:
1. Add an ElfCoreDump class for processing Linux core dump files, which will
later be used to implement the core dump to minidump conversion.
2. Add a CrashGenerator class for generating a crash with a core dump file
for testing the functionalities of ElfCoreDump.
3. Move some utility functions for reading/writing files to file_utils.h.

This patch is part of a bigger patch that helps merging the breakpad code

Specifically, this patch makes the following changes:
1. Add a SafeReadLink function that wraps sys_readlink() to resolve a
symbolic link but guarantees the result is NULL-terminated on success.
2. Refactor other source code to use SafeReadLink instead of readlink()
or sys_readlink().

This patch adds synth_elf::{StringTable,SymbolTable,ELF} classes to
produce in-memory ELF files to properly test the Linux symbol dumping
code. It also uses those classes to add some basic tests for
the WriteSymbolFile function.

compute file ID
At present, the Linux symbol dumper maps the ELF file into memory to
examine the debugging information it contains, but then also calls
google_breakpad::FileID::ElfFileIdentifier, which maps the ELF file into
memory again. Some of our object files are large; Mozilla's libxul.so is
1.1GiB. Trying to map such files twice can interfere with tools like
valgrind that map themselves into high addresses (in an attempt to stay out
of the way of ordinary programs).
The FileID class has another method, ElfFileIdentifierFromMappedFile, that
operates on an already-loaded image of the file; use that instead.

This patch avoids unnecessary use of the <cfoo> headers in files that don't
actually use the identifiers they declare in the std:: namespace.
It also changes some files to better conform with the "Names and Order of

outside functions.
This patch addresses two differences between Linux and Macintosh OS X STABS
data:
- StabsReader assumes that the STABS entries follow the conventions for
storing STABS data in object file sections (that is, .stabs and
.stabstr), rather than in the object files's linker symbol table. On Mac
OS X, STABS entries live in the Mach-O file's LC_SYMTAB load command,
along with all the other linker symbols; they are not grouped into units
by N_UNDF entries.
This patch adds a boolean argument to the StabsReader constructor
indicating whether the parser should treat N_UNDF entries as unit
boundaries; this argument should be true on Linux, and false on Mac. The
patch changes src/common/linux/dump_symbols.cc to pass this new argument.
- Mac OS X STABS place SLINE (line number) records immediately before the
FUN record for the function to which they belong, and the values of such
records are absolute, not relative to the function start.
This patch extends the parser to queue up such records and report them to
the handler when we do see the FUN record. The meaning of
StabsHandler::Line remains unchanged; existing handlers do not need to be
adjusted.
This patch also adds unit tests for the new parser behaviors.

All the other classes which receive debugging data from some sort of parser
and use it to populate a Module have names ending in "ToModule":
DwarfCUToModule, DwarfCFIToModule. Also, DumpStabsHandler doesn't actually
dump anything.
This patch renames the DumpStabsHandler class to StabsToModule, which is
more consistent and descriptive.

StabsReader simply applies a reinterpret_cast to treat the stab entry data
as an array of 'struct nlist' structures, making the parser specific on the
host endianness, word size, and alignment rules. On Mac OS X, a single fat
binary file may contain object files of different ABIs, of which the user
chooses one at run time.
This patch changes the parser to read the data using the google_breakpad::
ByteCursor class, which can handle different endiannesses and word sizes.
The StabsReader constructor now takes arguments indicating the endianness
of the data and the size of each entry's value field. The patch changes
src/common/linux/dump_symbols.cc to pass the new argument.
This patch changes the StabsReader unit tests to use the google_breakpad::
TestAssembler classes to generate test data, rather than reading it from a
file. This makes it easy to generate test data in various endiannesses and
word sizes. It also adds tests for the new parser behaviors.

At the moment, the mappings from register numbers appearing in DWARF CFI
and .eh_frame exception handling sections to the appropriate
processor-specific names are in src/common/linux/dump_syms.cc. However, the
numberings are (for the most part) the same on all platforms using DWARF,
so there's no reason those tables shouldn't be shared between the Linux and
Mac symbol dumpers.
This patch moves the tables into a nested class of DwarfCFIToModule, so
they the Mac dumper can use them when it is changed to use
DwarfCFIToModule.

The Linux symbol dumper's classes are reasonably portable, and should be

their unit tests. Update #include directives and Makefile.

by default.
In the process of pairing up DWARF source lines with the functions they
belong to, the dumper detects and warns about regions of functions that
have no source line information, and vice versa. However, this seems to
occur in real code frequently enough (although not often) that the warnings
may obscure more serious problems.
This patch makes those warnings disabled by default in
DwarfCUToModule::WarningReporter. It does not add a way for the dump_syms
user to enable them.

In order to dump call frame information held in .eh_frame sections, the
dumper needs to know the proper base address to use for pointers encoded
using the DW_EH_PE_textrel encoding. This should be the start of the .text
section. However, due to a cut-and-paste typo, the dumper was supplying the
base address of the ".got" section instead.
