MinGW headers are all lowercase, and because we build FF with MinGW
on Linux - capitalization matters. But if you're plugging along,
working on Windows, you might forget about that, and wind up
inadvertently breaking the MinGW build because you capitalized
an include file (as is common in Windows development.)
This lint job takes the list of header files from MinGW
(generated by cd mingw-w64/mingw-w64-headers &&
find . -name "*.h" | xargs -I bob -- basename bob | sort | uniq)
and will alert if they are in an #include statement but not
all-lowercase.

console.assert keeps the same semantics as NS_ASSERT in that it doesn't throw an exception,
but a lot of the places code was using it in a way that would be better served by throwing
an exception when the condition is false.

This changeset changes behavior.
If the profile is streamed before any JSContext has gone away, we now iterate
over the entire buffer twice (per thread): First, to collect information about
JIT frames, and then again when we build the JSON for the samples. The first
traversal stores small pieces of JSON for JIT fromes in individual strings, and
the second iteration splices those strings into the thread JSON's frame table.
When the JSContext for a thread goes away, we no longer build JSON for samples,
and we don't reset the profiler buffer. We now only build the JSON for JIT
frames. Once the complete profile is requested and we build samples for it, we
iterate over the entire buffer, and look up the cached JIT frame information for
JitReturnAddr entries from the correct range. Different parts of the buffer may
correspond to the life time of different JSContexts: For each JSContext we will
have one range in the JITFrameInfo, and we can look up the correct range based
on the buffer position of the JitReturnAddr entry that we're processing.
This new way of doing things has multiple advantages:
- We no longer reset the buffer, so we no longer lose information about other
threads.
- All threads from a given process now always have sample data for the same
time range. Before this change, the "partial profile" from a thread that
lost its JSContext could extend further into the past than the other threads'
profiles.
- Requesting profiles multiple times now has more consistent results. Before
this change, the first requested profile would include the partial profile,
but then the partial profile was discarded. And the second requested profile
would not contain any data for the time before the JSContext went away.
- We now do less work when a thread's JSContext goes away. This should
decrease the interruption time.

In an upcoming patch we'll want to initialize mUniqueStrings by stealing
another object's UniqueJSONStrings, but UniqueJSONStrings itself is not
move-constructible. But UniquePtr is.
Making UniqueJSONStrings itself move-constructible would be a bit tricky
because it has a SpliceableChunkedJSONWriter which is not move-constructible;
and making SpliceableChunkedJSONWriter move-constructible is hard because
there's no obvious "empty but valid" state that we could leave a moved-out-of
SpliceableChunkedJSONWriter in; for example, it expects to have a non-null
WriteFunc at all times.

already, through unified builds.

nsCString is the idiomatic string class we want to use anyway. There's no need

The file copies and renames make this patch look a bit confusing. Here's what
happens:
ThreadInfo.h:
Most of the code gets moved into RegisteredThread.h and ProfiledThreadData.h,
but a small piece remains in ThreadInfo.h.
ThreadInfo.cpp:
Gets split into RegisteredThread.cpp and ProfiledThreadData.cpp.
ThreadInfo.cpp itself goes away.
In the mercurial changeset, I've marked ThreadInfo.h as being copied to both
RegisteredThread.h and to ProfiledThreadData.h, and ThreadInfo.cpp as being
copied to RegisteredThread.cpp and as being renamed to ProfiledThreadData.cpp.

The overlay elements with children of editMenuOverlay.xul are moved into
include files (editMenuCommands.inc.xul and editMenuKeys.inc.xul). For
the other single elements in the overlay, the attributes are inlined
wherever they are used.

As of Bug 1425463 it's available in all contexts (including JSM). The following
patche is going to remove imports to Console.jsm, so prepare for this by allowing
it to be used as a global in eslint.
