* fix: Remove re cache internals manipulation
* fix: Purge re cache after module loads
Empty cache would work better as we already got our pre-compiled
patterns at the top level of every module. This leaves the cache open
for dynamically generated patterns which are in better need of it. Over
time, workers would converge to this anyway. This change only reduces
the cache hit and eviction effort.
I'd improve this by executing `re.purge` on every module import but
complexity tradeoff lol. I'd prefer if re didn't cache patterns
generated by `re.compile` but I dont see this behaviour or any escape
hatches so this will have to do for now.
* perf: preload more modules
- bleach is used frequently for sanitization
- File gets imported anytime a private file is viewed. Indirect import
of PIL is costly in each worker.
* test: warm up perf test
* fix: stale `frappe.local`

* fix: force re-init in request
To ensure that any one bad request can not completely cause recurring
loop of broken requests due to bad locals, we just force-init locals on
every request.

* Exceptions not supported by Frappe's WSGI (unsupported HTTP methods) may not be accessible to the after_request hooks - but the lack of active response may be an indicator / and peeking in the request
Moved before/after tasks in Requests as hooks for:

- releasing document locks
To reduce downtime reading from main db server during maintenance_mode
can be allowed. This lets users browse desk, static sites or any other
pages while ensuring that no writes happen to DB.

The license.txt file has been replaced with LICENSE for quite a while
now. INAL but it didn't seem accurate to say "hey, checkout license.txt
although there's no such file". Apart from this, there were
inconsistencies in the headers altogether...this change brings
consistency.
