Restructure GATTC 

This patch changes how GATTC is structured. Up till now, it
contained tBTA_GATTC_CACHE and tBTA_GATTC_CACHE_ATTR. Those
structures were so ugly, someone hide them inside internal
header, to make sure noone would ever access them from outside
GATTC. They are now replaced with:
tBTA_GATTC_SERVICE,
tBTA_GATTC_CHARACTERISTIC,
tBTA_GATTC_DESCRIPTOR and
tBTA_GATTC_INCLUDED_SVC.

Those looks much better, and were made globally avaliable.
Thanks to way they're build, we no longer need set of access
methods, which were also very ugly:
BTA_GATTC_GetFirstChar
BTA_GATTC_GetNextChar
BTA_GATTC_GetFirstIncludedService
etc.

This patch breaks HID, DO NOT SUBMIT without HID refactor.
