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.

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
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Add two convenient methods, back() and empty(), to the wasteful_vector
class.
2. Refactor the LinuxDumper class such that it can later be splitted into
a base class and two derived classes, one uses the current ptrace
implementation and one uses a core file.
3. Refactor the MinidumpWriter class such that it can later use different
derived implementations of LinuxDumper.

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 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
with the modified version in Chromium OS.
The MemoryRange class was added in r895 (http://breakpad.appspot.com/332001),
which is largely based on MMappedRange but generalized to be used in other
code. However, MemoryRange does not support minidump data structures. This
patch adds a MinidumpMemoryRange class that extends MemoryRange to handle
minidump data structures, which can then replace MMappedRange.
As with MemoryRange, MinidumpMemoryRange is unit tested.

Manufacturing an exception record improves the crash reporting, since then
the crashes get bucketed by the call stack leading to the dump, instead of
all falling into a misc bucket that nobody ever looks at.
Currently these are occuring through e.g. dumps from the base watchdog.

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 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().

with the modified version in Chromium OS.
Specifically, this patch makes the following changes:

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.

To be noted:
1) All is done in process, as multi-process is not allowed on ios.
2) Dump are saved when a crash occures but are not automatically send to the
server.
3) Breakpad.h contains function to check if a dump must be uploaded, and to
upload a dump.
4) The code is copy pasting a log of Breakpad implementation for Mac OS. It
might be possible to do some refactoring.

This function already establishes that (signed) i must be positive by the time
it assigns it to (unsigned) reg. Because reg is unsigned, it is impossible for
it to be negative. Because i was already checked for positivity, this check
can be removed entirely. It was not a miswritten check that intended to check
i instead of reg, because i is already checked.
This addresses the following warning:

symupload printed -[NSData length], an NSUInteger, using %lu. %lu is proper
to print a "long" as unsigned, but NSUInteger is a typedef for "unsigned int"
when building for 32-bit. This would not have caused any problems, because in
the 32-bit model, both int and long are 32 bits wide. In the 64-bit model,
long is 64 bits wide, but NSUInteger is defiend as "unsigned long", so there
wouldn't have even been a warning in that case.
This addresses the following warning:
symupload.m:137:30:{137:28-137:31}{137:46-137:59}: warning: conversion specifies type 'unsigned long' but the argument has type 'NSUInteger' (aka 'unsigned int') [-Wformat]

<Breakpad/BreakpadDefines.h>.
During the build of Breakpad itself (especially in Chromium), there is no
Breakpad.framework/Headers in which to locate BreakpadDefines.h, so the
framework-style #include of <Breakpad/BreakpadDefines.h> is not able to find
anything to #include. Using the "BreakpadDefines.h" form should always locate
this file next to Breakpad.h whether it's in the framework or in the source
tree.
This fixes a Chromium build regression caused by Breakpad r856.
