Fix Bug#36149 Read buffer overflow in srv0start.c found during "make test"

Use strncmp(3) instead of memcmp(3) to avoid reading past end of the string
if it is empty (*str == '\0'). This bug is _not_ a buffer overflow.

Discussed with:	Sunny (via IM)

Fix of issue# 4

Fixed a timing hole where a thread dropping an index can free the
in-memory index struct while another thread is still using
that structure to remove entries from adaptive hash index belonging
to one of the pages that belongs to the index being dropped.

The fix is to have a reference counter in the index struct and to
wait for this counter to drop to zero beforing freeing the struct.

Removed UNIV_INLINE qualifier from btr_search_info_get_ref_count().
Otherwise compilation failed on non-debug builds.
