Bug 1360308 offloads IO operations from the main thread when we create paired minidumps.
This breaks the symmetry of paired minidumps: the thread stacks of the parent minidump
doesn't correspond to the thread stacks in the child minidumps and renders the parent
stack useless. This patch moves generation of the parent minidump back to the main
thread to keep the context of the parent process when creating paired minidumps. Child
minidump is still created asynchronously.

We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

gcc throws a warning-as-error saying that the const qualifier will be ignored by function callers.
Remove the const qualifier to remove the warning.

This aligns the code more closely with how the input stream pump works: 0
available bytes when the stream itself told us it's ready means the stream is at
the end.
Note from asuth: This fix was originally part of bug 1371699, it was part 5.
However, its initial landing was backed out, but it is now very much needed for
bug 1393063, so I'm landing it.

Telemetry and some performance profiles show that Msg_NotifyIMEFocus can take
a few seconds to complete, and jank the browser. With bug 1217700, it removes
the necessity of sync Msg_NotifyIMEFocus, so in this patch we make this async
for performance improvement.

We were using std::vector::assign, which resizes the vector to
match the incoming data. This isn't what we want, as ranges_ has
already been sized to bucket_count_ + 1. Instead, just use a
copy.

When removing our Windows message loop pumping code in the content
process, a11y code on the MTA thread must have some way to wake up the
main thread. The main thread could be blocked either on a conditional
variable waiting for a Gecko event, or it could be blocked waiting on
a Windows HANDLE in IPC code (doing a sync message send). In the
former case, we wake it up by posting an event to the main thread. In
the latter case, we continue to use the asynchronous procedure call
mechanism.

There are two problems related with EVENT__SIZEOF_OFF_T:
- When building Firefox with -D_FILE_OFFSET_BITS=64, off_t is 64 bits,
but the in-tree event-config.h still defines EVENT__SIZEOF_OFF_T to 4.
- When building Firefox *without* -D_FILE_OFFSET_BITS=64 (the default)
against a system libevent that was built with -D_FILE_OFFSET_BITS=64,
its event-config.h defines EVENT__SIZEOF_OFF_T to 8, which then
doesn't match off_t size.
For the latter, libevent actually defines its own off_t type, that
callers are supposed to use instead of off_t. So that's what our
static_assert should be checking.

This patch also adds logging into ResolveJunctionPointsAndSymLinks to help diagnose issues that
might arise if the resolution fails or the path is not usable for some reason.
The log and exp calls in base::Histogram::InitializeBucketRange()
were showing up in profiles. This patch uses the precomputed
buckets for exponential histograms instead of computing them at
runtime. Though linear histograms do show up in the profile that
prompted this change, they contribute much less, and due to the
trivial nature of generating these, it's unlikely that a static
cache would provide much if any speedup.

Having these functions declared in the class definition and therefore
inlined means that every call site is bloated by having to store the
argument so its address can be taken and load the sizeof() constant.
There's no good reason that we should be doing this; the Read*
counterparts are also out-of-lined, which hasn't seemed to cause any
problems. Moving these out-of-line saves about 200K (!) of space on
x86-64 Linux.
