Because not all static components are using the static registration yet,
we can end up in situations where a same component is registered
multiple times, which can have some unexpected consequences.
Interestingly enough, this change revealed that we did have static
registration in place for components that were kept under the old system
after bug 1478124 and bug 1524687.
There are also possibly some non-obvious things that can happen while
migrating the remaining components, like what happened to me while I
worked on @mozilla.org/widget/components;1 (see bug 1542214 comment 0).

Bug 1478124 and bug 1524687 converted many things to static xpcom
component registration, but somehow left the corresponding C++
initialization.

Originally, RDD reused the GPU process selector since they were
using all the same services, and it reduced the number of places
that had to be touched. Now that RDD needs pref handling, it
needs its own process selector to avoid GPU inheriting pref
handling.

Before bug 938437, we had a rather large and error-prone
nsStaticXULComponents.cpp used to register all modules. That was
replaced with clever use of the linker, which allowed to avoid the mess
that maintaining that file was.
Fast forward to now, where after bug 1524687 and other work that
preceded it, we have a much smaller number of remaining static xpcom
components, registered via this linker hack, and don't expect to add
any new ones. The list should eventually go down to zero.
Within that context, it seems to be the right time to get rid of the
magic, and with it the problems it causes on its own.
Some of those components could probably be trivially be converted to
static registration via .conf files, but I didn't want to deal with the
possible need to increase the number of dummy modules in XPCOMInit.cpp.
They can still be converted as a followup.

Mechanical change from Matcher::match(...) to Matcher::operator()(...).
This will now permit the use of generic lambdas, and facilitate the
implementation of multi-lambda match.

clang's -Wmissing-prototypes option identifies global functions that can be made static (because they're only called from one compilation unit) or removed (if they're never called). The .cpp files defining these functions did not include the headers with the corresponding function prototypes used by other compilation units. Including a header file in its corresponding .cpp file can help catch mismatched declarations and definitions.

With most of the JS components converted to static registration, the string
arena and component hashtables are much smaller than the minimum space we
allocate for them.
