6f8238e1e9 mdbx: LCK-format version 3. 
The LCK file is re-created at every opportunity when the process that
opens the database is the only one that works with it. Thus the change
of the format of the file LCK creates only minimal compatibility
problems.

Applications using different versions of _libmdbx_ will be able to work
with one database alternately, but not at the same time. This appears to
be an acceptable inconvenience in exchange for new features.

0b8ac37450 mdbx: reduces number of getpid() calls for checking PID against fork(). 
PID check could be ommited:
 - on Linux when madvise(MADV_DONTFORK) is available. i.e. after the fork()
    mapped pages will not be available for child process.
 - in Windows where fork() not available.

3c4e9443ae mdbx: allow devel-signatures (for Miranga-NG). 
Binary format of v0.1.x and v0.2.x is frozed.

This commit allows to open DBs created early by devel-versions of libmdbx.
It seems to be required for Miranda-NG users, but no one else.
