core: reduce the usage of global variables

* move all the 'logging' related global variables into ctx
* make gf_fop_list a 'const' global array, hence no init(),
  no edits.
* make sure ctx is allocated without any dependancy on
  memory-accounting infrastructure, so it can be the first
  one to get allocated
* globals_init() should happen with ctx as argument

not yet fixed below in this patchset:
* anything with 'THIS' related globals
* anything related to compat_errno related globals as its
  one time init'd and not changed later on.
* statedump related globals
