Avoid naming conflicts with other mdb* packages. Bump version to 0.9.5

With MDB_MAPASYNC, the API provided no way to ensure full sync.

It returned 0, which is the freelist DBI and is valid for a few uses.

This allows for other flag values in the future.

Let the user specify the number of databases he will actually
use. Adding 2 for FREE_DBI and MAIN_DBI is an internal matter.

mdb_env_open() with these flags did not open a synchronizing
file descriptor.  Thus disabling them later did not work.

Drop mmap()'s MAP_FIXED flag, so it returns another address instead
of unmapping existing overlapping pages. Verify the returned address.

MDB_NOSUBDIR was == MDB_REVERSEKEY. That affected the freelist:
Env flags are stored in mm_flags alias mm_dbs[FREE_DBI].md_flags.

It stays a persistent flag, in case mdb_env_open someday wants
to pick/verify which lockfile to use with the datafile.

Catch bad flags so they will no longer make it into the data file.

Also allow the max to be redefined at compile time. Of course, there is no
legitimate reason to do so.

Of course, no one would ever have any legitimate reason to set these
items to anywhere near such extreme values in the first place.

If a timeout is set, perform the SSL Handshake using non-blocking IO.  This way
we can timeout if SSL Handshake gets stuck for whatever reason.

This code is currently hidden behind #ifdefs (LDAP_USE_NON_BLOCKING_TLS) and
disabled by default as there seem to be some problems using NON-blocking
I/O during the TLS Handshake when linking against NSS (either a bug in NSS
itself of in tls_m.c, see discussion on -devel)

This patch adds an additional parameter to ldap_int_poll() in order to indicate
if we're waiting in order to perform a read or write operation.

do not expose control until deref overlay is actually instantiated at least
once (see also ITS#6647)

Wasn't pushing the optimal half of the array onto the stack,
thus used more stack than expected -> overrun.
