Add context state to be used in syntax conversion functions

Metze, Andrew,

Could you please check following commit:

<http://git.samba.org/?p=kamenim/samba.git;a=commitdiff;h=91ade0b664aa69fffce500025037db76d8c72702>It
is a small part of what should be done and is intended as a sample
of what I want to do. I wanted to hear what you think first, as this will
affect the code in quite some places,

Basically what I want is to have convert-context to be passed in syntax
conversion functions - drs-to-ldb, ldb-to-drs, object_convert etc.
We need to know in what context those functions are used in order
to make values the same way Windows does.

I also think this is the right way to handle cases like
'relax_OID_conversions'
flag used during vampire/replication - this flag is currently in dsdb_schema
definition which is wrong IMHO, as it defines how OID-syntax-conversion
functions
should work, rather than schema objects.
