The current code for resizing PLDHashTable modifies the cached hash for
all entries in the old hash table. This is unnecessary, because we're
going to throw away the old hash table shortly, and inefficient, because
writing to memory we're never going to use again just wastes time and
memory bandwidth. Instead, let's avoid the write by pulling out the
cached key and doing the necessary manipulation on local variables,
which is probably slightly faster.
This alters nsILoadURIDelegate.loadURI() to return a Promise rather than spinning the event loop to synchronously return a boolean, and alters nsDocShell::InternalLoad to allow for those changes by re-calling itself if necessary based on the resolution of the promise.
Similar to the previous part, we convert mBreakpadId to an nsCString to
avoid issues with locale-dependent std::string operations.
There are a lot of non-profiler changes here because a bunch of things
depend on the SharedLibrary object that the profiler defines.
Later patches add support for Windows. OS-X will need a follow-up.

The only real way to get memory mapping information on Linux is to read and
parse /proc/self/maps, and infer information about a specific pointer based on
its contents.
This patch adds a helper which parses the entire contents of smaps, and
returns an array of objects describing each region. It also updates resident
unique reporter to use that helper. Later patches use it to map stack base
addresses to VM regions, and report their usage data.

This change stores the base allocation address and actual allocated stack size
(as opposed to the requested size, which may be 0), so that we can map them to
VM regions in a memory reporter.

I initially tried to avoid this, but decided it was necessary given the number
of times I had to repeat the same pattern of casting a variable to void*, and
then casting it back in a part of code far distant from the original type.
This changes our preference callback registration functions to match the type
of the callback's closure argument to the actual type of the closure pointer
passed, and then casting it to the type of our generic callback function. This
ensures that the callback function always gets an argument of the type it's
actually expecting without adding any additional runtime memory or
QueryInterface overhead for tracking it.

Adding or removing an FD from this API currently requires changes in about a
half dozen places. Ignoring the Java side of things. This patch changes the
API to pass a struct, rather than additional arguments for each FD, so that
adding and removing FDs only requires changing one declaration, and the two
call sites that add and consume the FDs.
