**
**  EXTERNAL call format: status = psq_call(PSQ_BGN_SESSION, &psq_cb, &sess_cb);
**
** Description:
**      The psq_bgn_session function begins a parser session.  It should be
**	called each time a new user connects to a server.  There may be 
**      many parser sessions per database server.  There should be one parser 
**      session for each invocation of the database system that is connected 
**      to the server.  When starting a parser session, one has to tell it
**	what query language to use, and other session parameters.
**
** Inputs:
**      psq_cb
**          .psq_qlang                  The query language to use.
**          .psq_decimal
**		.psf_decspec		TRUE indicates that the decimal marker
**					has been specified.  FALSE means use the
**					default (a ".").
**		.psf_decimal		The character to use as a decimal marker
**					(if specified).
**	    .psq_distrib		Indicator for whether distributed
**					statements and constructs should be
**					accepted.
**	    .psq_sessid			Session id 
**	    .psq_server			address of server control block
**	    .psq_adf_cb			Pointer to session's ADF_CB
**	    .psq_dbid			Database id for this session.
**	    .psq_user			User name of 
**	    .psq_dba			User name of dba
**	    .psq_group			Group id of session
**	    .psq_aplid			Application id of session
**	    .psq_flag			bitmask containing the following flags:
**	      .psq_catupd		  TRUE means catalogs updateable
**	      .psq_warnings		  Set to TRUE if user wishes to see
**					  warnings on unsupported commands
**	    .psq_idxstruct		Structure for creating new indexes
**					(e.g. DB_ISAM_STORE)
**	    .psq_udbid			Unique database id for this session.
**	    .psq_ustat	 		User status flags from SCS_ICS
**	    .psq_dbxlate		Case translation semantics for the db
**	sess_cb				Pointer to session control block
**					(Can be NULL)
**
** Outputs:
**      psq_cb
**          .psq_error                  Error information
**		.err_code		    What error occurred
**		    E_PS0000_OK			Success
**		    E_PS0001_INTERNAL_ERROR	    Internal PSF problem
**		    E_PS0201_BAD_QLANG		    Bad query language specifier
**		    E_PS0203_NO_DECIMAL		    No decimal marker specified
**		    E_PS0204_BAD_DISTRIB	    Bad distributed
**						    specification
**		    E_PS0205_SRV_NOT_INIT	    Server not initialized
**		    E_PS0206_TOO_MANY_SESS	    Too many sessions at one
**						    time
**	Returns:
**	    E_DB_OK			Function completed normally.
**	    E_DB_WARN			Function completed with warning(s)
**	    E_DB_ERROR			Function failed; non-catastrophic error
**	    E_DB_SEVERE			Session is to be aborted
**	    E_DB_FATAL			Function failed; catastrophic error
**	Exceptions:
**	    none
**
** Side Effects:
**	    Causes memory to be allocated.
**	    Increments the session count in the server control block.

**	10-aug-93 (andre)
**	    fixed cause of a compiler warning
**	08-sep-93 (swm)
**	    Changed sizeof(DB_SESSID) to sizeof(CS_SID) to reflect recent CL

**	20-sep-93 (rogerk)
**	    Changed default table create semantics to be WITH JOURNALING.

**	17-dec-93 (rblumer)
**	    "FIPS mode" no longer exists.  It was replaced some time ago by
**	    several feature-specific flags (e.g. flatten_nosingleton and
**	    direct_cursor_mode).  So I removed all FIPS_MODE flags.
**	02-jan-94 (andre)
**	    if starting a local session, call DMF to determine whether the
