This allows people to use repo to manage the checkout instead of gclient.
This helps when you're used to the standard repo+gerrit workflow that the
Android & Chromium OS projects use.

Previously, if the input file was missing, the symupload tool on Mac
would happily process, try to parse it (calling a method on nil) and
fail when trying to create the payload to send to the server as one
of the method raised a NSInvalidArgumentException when receiving a
nil value.
Change to code to instead check the file for existence which makes it
easier to understand what is happening when part of the build system
is misconfigured and invoke symupload without first creating the symbol
file.

Patch from Thomas Zimmermann <tzimmermann@mozilla.com>.
On Linux, breakpad relies on /proc/[pid]/maps to associate symbols from
addresses. ChromeOS' hugepage implementation replaces some segments
with anonymous private pages, which is a restriction of current
implementation in Linux kernel at the time of writing. Thus, breakpad
can no longer symbolize addresses from those text segments replaced by
hugepages.
This patch tries to recover the mappings. Because hugepages are always
inserted in between some .text sections, it tries to infer the names and
offsets of the segments, by looking at segments immediately precede and
succeed them.
For example, a text segment before hugepage optimization
02001000-03002000 r-xp /opt/google/chrome/chrome
can be broken into
02001000-02200000 r-xp /opt/google/chrome/chrome
02200000-03000000 r-xp
03000000-03002000 r-xp /opt/google/chrome/chrome

Patch from Ting-Yuan (Leo) Huang <laszio@chromium.org>.
This change is resolving an issue that was caused by the combination of:
- Android system libraries being relro packed in N+.
- Breakpad dealing with relro packed libraries in a hack way.
This is a fix for http://crbug/611824.
I also found an use-after-free issue (bug in Minidump::SeekToStreamType). I disallowed the MinidumpStreamInfo copy and assign constructors and the compiler detected another similar issue in Minidump::Print. Then I disabled the copy and assign constructors for most classes in minidump.h (just in case). There are a couple of classes where I couldn't disallow them (since assign is used). This will require a small refactor so I left it out of this CL.

__builtin_trap() causes a SIGTRAP on arm64 (at least with GCC 4.9).
SIGTRAP is not handled by breakpad, causing crashes induced by
__builtin_trap() to be missed.
Note that on x86 and arm, instead, __builtin_trap() raises a SIGILL,
which is already handled by breakapd.

Some of my colleagues have commented in the past few months that the
Breakpad README is not very clear on how to get and build the code
nowadays. This change moves some of the docs from the "request
change review" section up to the "getting started" section, and adds
a few more things to clarify.

Patch from Veljko Mihailovic <veljko.mihailovic@imgtec.com>.
src/client/linux/minidump_writer/minidump_writer.cc:273 obtains the
stack info by calling GetStackInfo(). That method will return the
stack base address, aligned to the bottom of the memory page that
'stack_pointer' is in. After that it will cap the size of the memory
area to be copied into the minidump to 'max_stack_len', starting from
the base address, if the caller requested so. This will be the case
when collecting reduced stacks, as introduced by this change:
https://breakpad.appspot.com/487002/
In such cases the caller will request 2048 bytes of memory. However
GetStackInfo() will have aligned the base address to the page
boundary, by default 4096 bytes. If the stack, which grows towards the
base address from the top ends before the 2048 bytes of the first
block, then we will not collect any useful part of the stack.
As a fix we skip chunks of 'max_stack_len' bytes starting from
the base address until the stack_pointer is actually contained in the
chunk, which we will add to the minidump file.

When a crash occurs as a result of an allocation failure, it is useful
