I changed my FreeBSD locate to support multiple databases (option or
environment). I fixed also broken locate.bigram and locate.code. It
works well but I don't think my code style is ready for a commit.

New options

	   -S	  Print some statistic about database and exit.

	   -c	  Suppress	normal	output; instead print a count of
		       matching file names.

	   -d database
		       Search in database instead the default file name
		       database.

		       Multiple option -d allowed and use different databases
		       Or in other words, the last -d don't overwrite the pre-
		       vious -d

		       database may be a colon-separated list of databases. A
		       single colon is a reference to the default database.

		       $ locate -d ~/lib/mydb: foo

		       search first in ~/lib/mydb and then in
		       /var/db/locate.database.

		       Read from standard input if file name - is given.  For
		       example, you can compress your database and use:

		       $ zcat database.gz | locate -d - pattern

		       This maybe useful on machines with fast CPU and few RAM
		       and slow I/O. Note: you can only use  *one* pattern for
		       stdin.

	   -i	  Ignore  case  distinctions  in both the pattern and the
		       database.

	   -l number   Limit output to number of file names and exit.

	   -m	  use mmap(2) instead stdio library, default. In most
		       cases faster.

	   -s	  use stdio library instead mmap(2).
