Adam Duke f6974b15ef namespace implementations of FileID
In trying to create a backend service that can process both ELF and
Mach-O binaries, I found that symbol collisions occur when trying to
link different implementations of FileID. This change puts the
different implementations into separate namespaces to avoid the
collision.

Ted Mielczarek 8bb3d55af7 Rename src/common/memory.h to memory_allocator.h.
memory.h shadows a system header which normally isn't a problem
because of the include paths in Breakpad, but the Firefox build
system winds up with src/common in the include path so we've had
a workaround for this for years. Renaming the file lets us get
rid of that workaround and shouldn't hurt anything.

Ted Mielczarek 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.

Ted Mielczarek 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.

If FileID was constructed with a path that was >= PATH_MAX then path_ was not terminated resulting in a possible buffer overrun when reading.

benchan@chromium.org 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.
