library init: be recursive

Previously, a single call to ares_library_cleanup() would deinitialise
the c-ares library, regardless of how many times ares_library_init() was
called. This behaviour may cause problems in programs linking two or
more libraries which, in turn, use c-ares. The present commit fixes this
problem, deinitializing the library only after a number of calls to
ares_library_cleanup() matching the number of calls to
ares_library_init().
library init: documentation update

This commit updates the documentation of ares_library_init() and
ares_library_cleanup() with regard to the newly introduced reference
counting of initializations and deinitializations.
ares_parse_txt_reply: return a ares_txt_reply node for each sub-string

one.
