encoding: initialize jsonmap when module is loaded
This makes jsonescape() a thread-safe function, which is necessary for hgweb.
The initialization stuff isn't that slow:
$ python -m timeit -n1000 -s 'from mercurial import encoding as x' 'reload(x)'
original: 1000 loops, best of 3: 158 usec per loop
this patch: 1000 loops, best of 3: 214 usec per loop
compared to loading the commands module:
$ python -m timeit -n1000 -s 'from mercurial import commands as x' 'reload(x)'
1000 loops, best of 3: 1.11 msec per loop
