Single json buffer (#2336)

Browse Source 
* Single/static JSON buffer for all requests.

* Missing json.cpp changes.

* Async fix.

* Added conditional compile (WLED_USE_DYNAMIC_JSON).

* Advanced locking with time-out.

* Missing releaseJSONBufferLock() on error response.

* Fix for config saving.

* Fixes and optimisations.
Dadded debugging information.

* Fix for ledmaps.

* No unsolicited serial sending if GPIO1 allocated

* Stray semicolons

* Fix JSON ledmap
