* make LDAP use this instead of the hacky previous method to specify
the DN to bind as
* make all auth options behave the same when they are not compiled
into the server
* rename "ident maps" to "user name maps", and support them for all
auth methods that provide an external username
This makes a backwards incompatible change in the format of pg_hba.conf
for the ident, PAM and LDAP authentication methods.

file when it's being reloaded, instead of silently reloading a broken
file and failing only when a user tries to connect.
This patch also makes the "sameuser" argument to ident authentication
optional.

manually release the LDAP handle via ldap_unbind(). This isn't a
significant problem in practice because an error eventually results
in exiting the process, but we can cleanup correctly without too
much pain.
In passing, fix an error in snprintf() usage: the "size" parameter
to snprintf() is the size of the destination buffer, including space
for the NUL terminator. Also, depending on the value of NAMEDATALEN,
the old coding could have allowed for a buffer overflow.
