Revbump for MySQL default change

Log message:
Drop "55" (php55) from PHP_VERSIONS_ACCEPTED.

Log message:
Explicitly restrict PHP_VERSIONS_ACCEPTED to 55 and 56 for packages which
use php-mysql package.

Log message:
Remove mk/find-prefix.mk usage from the databases category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Fix build of packages depending on mariadb55-client

When a package depends on mysql-client, in includes mk/mysql-buildlink3.mk
and may get buildlinked with mariadb55-client if MYSQL_VERSION_DEFAULT is
set to MARIADB55.

mariadb55-client's buildlink3.mk defined BUILDLINK_*.mariadb-client
variables, wich caused build problems with packages expecting
BUILDLINK_*.mysql-client to be defined. For instance, php-pdo_mysql
expectex BUILDLINK_PREFIX.mysql-client to be set and fails to build
without it.

Fix the problem by changing BUILDLINK_*.mariadb-client to
BUILDLINK_*.mysql-client in mariadb55-client/buildlink3.mk. Remove a
package specific woakrround for this exact ptoblem in php-mysqli.

NB: commit log on pkgsrc/databases/mariadb55-client/buildlink3.mk 1.2-1.3
and pkgsrc/databases/php-mysqli/Makefile 1.12-1.13 was truncated. This
change just adds a comment to the first file and a null-commit to the
second file to have an oportunity to provide the full cvs log.

Log message:
Add optional support for mysqlnd (MySQL Native Driver). Removes the need to \ 
build against and link the mysql-client package.

Log message:
Reset PKGREVISION by update of both php53 and php54.

Log message:
Bump PKGREVISION for mysql default change to 55.
