The first module in a minidump is expected to be for the main executable.
We used to assume that /proc/<pid>/maps always showed that one first, but in
some cases that is no longer true (see comment #7 of the bug). So this
change makes use of the entry point stored in auxv to make sure we put the
correct module first.

Change MinidumpModuleList::GetMainModule() to use GetModuleAtIndex() instead
of GetModuleAtSequence() because the former gets the first module that was
in the minidump file, while the latter actually gets the first module when
sorted by address. While this is pretty much the same thing at the moment,
I have another change in the works that can sometimes affect the module
order in the file.

Instead of using exc_server, the message is parsed directly, and the minidump
is created, then the app is killed.
Moreover, the only catch exception is exception_raise. This patch remove all
rereference to exception_raise_state and exception_raise_state_identity.

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.

it's actually still needed on that OS release. There isn't a way to get the
functionality Breakpad needs from it without calling it until 10.6.

This patch allows Breakpad's DWARF reader to at least read or skip
attributes using the new forms defined in version 4 of the DWARF
specification, instead of crashing.
Attributes encoded using DW_FORM_flag_present, DW_FORM_sec_offset, and
DW_FORM_exprloc should work fine now. However, compilation units using
DW_FORM_ref_sig8 to refer to types in .debug_types will need further work
to support. (GCC 4.6.2 does not emit .debug_types sections.)
Specifically:
- dwarf2reader::DwarfForm gets new values.
- dwarf2reader::Dwarf2Handler and dwarf2reader::DIEHandler get new handler
methods, named ProcessAttributeSignature, for DW_FORM_ref_sig8 attributes.
- dwarf2reader::CompilationUnit reads DW_FORM_ref_sig8 attributes, and
passes them to ProcessAttributeSignature. It also gets support for
DW_FORM_sec_offset, DW_FORM_exprloc, and DW_FORM_flag_present, using the
existing appropriate ProcessAttribute* methods.
- dwarf2reader::DIEDispatcher passes through ProcessAttributeSignature
attributes to its DIEHandler.
- Unit tests are updated.

When a variable is used to set (and lookup) MappingInfo's "start_addr"
field, it needs to match types -- which is "uintptr_t". When Chrome OS
updated the 'make' that's used for building, the 32-bit "char *" had
sign-extended when cast up to a u_int64_t -- maybe because pointers were
unsigned before and then changed to be signed -- and that caused the address
lookup to fail.

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.
