Backport change from trunk:
docs/quickstart.rst: Fix seriously outdated statement that Xapian
doesn't create the database directory - that changed in 0.7.2
(release 2003-07-11), pointed out by aarsh on #xapian.

Backport changes from trunk:
HACKING,Makefile.am: With lcov 1.10, we no longer need any of our
hacky workarounds, so make this a requirement and simplify the rules
in the makefile.
Makefile.am: Pass -f to lcov, which should avoid the need for the
patch we've been applying to lcov.
