This is a particularly nice example of how iterators can be so much nicer than
Enumerate()-style functions:

nsBaseHashtable has both EnumerateRead() and Enumerate(). A comment claims that
the latter locks the table, but this is false, so I removed the comment. Other
than that the only notable difference between them is that they have slightly
different types for dealing with values (|UserDataType| vs |DataType&|) so I've
implemented both GetUserData() and GetData(), allowing either type to be used.
Using g_slice_set_config() fails with newer glib because the slice allocator
now has a static constructor that runs when glib is loaded, consequently
emitting a noisy error message which confuses people into believing it's the
root of their problems.
The only way left to force the slice allocator to use "system" malloc (in
practice, jemalloc) is to set the G_SLICE environment variable to
always-malloc, and that needs to happen before glib is loaded.
Fortunately, the firefox and plugin-container executables don't depend on
glib. Unfortunately, webapprt does, so the problem remains for web apps
running through it. xpcshell and other executables that depend on libxul
directly (as opposed to loading it dynamically) are not covered either.
Adding isMainProcessScriptable() into the middle of nsIInterfaceInfo
caused problems with some binary addons that relied on the ordering of
the methods in nsIInterfaceInfo. In an attempt to placate those addons,
move isMainProcessScriptable() to the end of the vtable. This change is
a no-op for normal libxul usage.
The original motivation for the Iterator/RemovingIterator split was that
PLDHashTable Checker class would treat them differently. But that didn't end up
happening (see bug 1131308). So this patch merges them. This is a small code
size win now but it will become bigger when I add iterators to nsTHashTable and
nsBaseHashtable.
The only complication is that PLDHashTable::Iter() is now non-const, which is
a problem if you use it in a const method. So I added PLDHashTable::ConstIter()
which is used in just two places. It's a bit of a hack -- effectively a
const_cast -- but I don't think it's too bad.
- Its move constructor was moving |aOther.mTable| instead of |aOther|. This
meant that |aOther| wasn't being zeroed out appropriately.
- test_pldhash_RemovingIterator() was testing Iterator's move constructor
instead of RemovingIterator's move constructor, due to a copy/paste
mistake.
