fbfd41af5f Simplify ELF parser code.
The layout of Elf32_Nhdr and Elf64_Nhdr is the same, so remove
templating and code that extracts the elfclass from the ELF file.

Testing: "make check" and breakpad_unittests when patched into
chromium.

c44217f646 Dump INFO CODE_ID containing Build ID in Linux dump_syms
I'd like to have the Build ID available for our symbol server
uploading, and this will make it easy.

Most of this change is me rewriting dump_symbols_unittest to be
typed tests so I could add a new test there.

6c8f80aa8b Switch the Linux minidump writer to use MDCVInfoELF for CV data.
This preserves full build ids in minidumps, which are useful for
tracking down the right version of system libraries from Linux
distributions.

The default build id produced by GNU binutils' ld is a 160-bit SHA-1
hash of some parts of the binary, which is exactly 20 bytes:
https://sourceware.org/binutils/docs-2.26/ld/Options.html#index-g_t_002d_002dbuild_002did-292

The bulk of the changes here are to change the signatures of the
FileID methods to use a wasteful_vector instead of raw pointers, since
build ids can be of arbitrary length.

The previous change that added support for this in the processor code
preserved the return value of `Minidump::debug_identifier()` as the
current `GUID+age` treatment for backwards-compatibility, and exposed
the full build id from `Minidump::code_identifier()`, which was
previously stubbed out for Linux dumps. This change keeps the debug ID
in the `dump_syms` output the same to match.

561f818735 Chrome on Android now supports loading the shared library directly from the APK file.
This patch makes two changes to breakpad to enable crash reporting to work correctly when the library is inside another file (an archive):

- Do not filter mappings which map an executable at a non-zero offset.
- If such an executable is mapped look in the ELF information for the
shared object name and use that name in the minidump.

Note this change doesn't care about the archive format and isn't Android
specific (though loading the shared library this way is currently only done on Android).

f044345c23 Refactor code in preparation of merging with the fork in Chromium OS.
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. Add a MemoryRange class for encapsulating and checking read access
   to a contiguous range of memory.
2. Add a MemoryMappedFile class for mapping a file into memory for
   read-only access.
3. Refactor other source code to use MemoryMappedFile.

BUG=455
TEST=Tested the following:
1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6.
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 minidump-2-core to covnert a minidump file to a core file.

e193098543 Breakpad: Avoid using the C++ <cfoo> headers.
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
Includes" rules in the Google C++ Style Guide.
