This patch removes C++ code related to reading in XPT information from
files. (Code related to packaging XPT files will be removed in the
next patch.) This includes code in the manifest parser, in addition to
the actual code for parsing files.
XPT information is now loaded directly from a single static data
structure, XPTHeader::kHeader, which will be automatically generated
at compile time from .idl files (via .xpt files). Note that the script
to do that is not added until part 6 of this patch series, so linking
will fail on parts 2 through 5.
I inlined XPTInterfaceInfoManager::RegisterXPTHeader into the ctor,
because that is the only caller. It feels like the lock there should
not be needed any more, but I left it alone for now.
The forward declaration of XPTArena in xptiprivate.h is needed because
it was being bootlegged via xpt_xdr.h. Some of the data structures in
reflect/xptinfo/ (which wrap the xpt_struct.h data structures) are
still allocated using XPTArena. Hopefully we can get rid of that in
followup work.
I also deleted a lot of comments in xpt_struct.h that talk about the
on-disk format. I also deleted checking of the major version number,
because that should not matter when the XPT information is baked into
the executable.

Manifest entries can contain flags, one of which allows to match on the
os running Gecko. The match is performed against the value returned by
nsIXULRuntime.getOS, which itself comes from the build-system's
OS_TARGET.
In practice, this means that things like os=WINNT, os=Darwin,
os=Android, os=Linux are valid filters, but the latter is too specific,
and most of the time, one would want something that is "any OS but
WINNT, Darwin, Android", which can't be expressed with manifest entry
flags (there is no "and" for them, only "or").
For convenience, we add the keyword "LikeUnix", which has that meaning.

Change mozilla::Smprintf and friends to return a UniquePtr, rather than
relying on manual memory management. (Though after this patch there are
still a handful of spots needing SmprintfFree.)
