I dug into a particular profile via KCachegrind (specifically the
profile for DirectParsoidClientTest in VisualEditor) and found this
surprising bottleneck. Let's say a test uses a data provider to test
a particular piece of code with 5 different languages. And then
another piece of code with 5 languages. And so on. Because the cache
can only hold 4 languages there will never be a successfull cache
hit.
The items in the cache are something like 1 or 2 megabytes each. It
should be fine to hold 16 of them in memory. Possibly even more. The
sweet spot in my example was 10. This is when the runtime of
DirectParsoidClientTest gets suddenly cut in half.

This reverts change I50c3d1c5df (commit b0317287bc), thus reinstating
change I7d690a1172 (commit d139eb07fe). The only change from the
original is in getHookMethodName(), additionally replacing '-' with '_'
(not just ':' and '\'). The original commit message follows:
This converts all hook handlers to the same internal representation.
This is done lazily, when the hook is run for the first time.
The logic for temporarily disabling handlers by calling scopedRegister()
with the $replace parameter set has been greatly simplified.
There are some minor changes to the class's interface and behavior,
none of which should be breaking changes:
* run() will emit deprecation warnings if and only if it was called
with the deprecationVersion option set, for all kinds of handlers.
The idea is that deprecated hooks should emit a warning either from
run(), or from emitDeprecationWarnings(). The latter happens if the
hook is listed in DeprecatedHooks.
* register() now also accepts hook handlers declared in the way that
extensions register hooks.
* Attempts to call register() with an invalid hook definition now
result in an invalidArgumentException.
* Attempts to call register() for a deprecated hook will consistently
result in a deprecation warning.
* The internal getRegisteredHooks() method has been removed in favor
of the identical getHookNames() method.
* The internal getLegacyHandlers method has been removed in favor
of getHandlerDescriptions() and getHandlerCallbacks().
* The call order changed so that dynamically registered handlers
are called last, instead of getting called before handler objects
from extensions.

This apparently caused some change in how hook handlers are called (it
now calls e.g. AbuseFilterHookHandler::onAbuseFilter-generateUserVars()
instead of AbuseFilterHookHandler::onAbuseFilter_generateUserVars()),
causing both test failures and errors on Beta.
This reverts commit d139eb07fe.
