locale.c: Swap the order of two functions
The new ordering will make the diffs less in the next commit, and will
make just as much sense going forward as the previous ordering.

locale.c: Pass locale to strftime functions
This will allow a future commit to reduce the amount of time spent in a
critical section.
It requires the least duplication of code for this commit to create a
new function sv_strftime_common() which takes over the bulk of the code
from sv_strftime_tm(), which becomes just a small wrapper. The new
function adds a 'locale' parameter, and the other functions that now
need to know the locale get it, and then call this new function.

locale.c: Shorten critical section times
Toggling a category's locale has a cost, so if there are a bunch of
operations that are going to be done in a row in a particular toggled
state, it makes sense to toggle once, do them all, then toggle back.
Most of the toggling in this file is short term, but there are a few
places where it is advantageous to toggle once.
But on some Configurations, toggling creates a critical, uninterruptible
section. For these, keeping the amount of time spent in such a state
without letting other threads execute needs to be as short as feasible,
and this outweighs the cost of toggling and retoggling.
This commit balances these competing needs by creating new macros for
those cases where we want to have an overarching toggle. Those macros
become no-ops when the toggling creates an uninterruptible section.
Thus, when there is a cost to remaining toggled for longer periods,
those macros don't do anything, and the macros that are at the point of
the actual need are the ones that do the toggling/retoggling. In the
Configurations where there isn't such a cost, the overarching macros
kick in, and the shorter-term ones find that the state is already
toggled, and they return without doing anything.
