ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7350
TITLE:       SKIP LOCKED clause for SELECT WITH LOCK, UPDATE and DELETE
DESCRIPTION: test verifies ability to get records from table which already has several locked rows by another transaction.
             Check performs for several type of queries:
                 1) DSQL 
                 2) PSQL which uses static SQL code
                 3) PSQL which uses ES/EDS mechanism.
             Two type of access mode is checked: READ and READ_WRITE
             Both WAIT and NO WAIT modes are used, but for WAIT we have to skip exectuion for TABLE STABILITY.
             All kinds of transaction isolation levels are involved: TABLE STABILITY; SNAPSHOT; RC READ_CONSISTENCY; RC REC_VER and RC NO_REC_VER.
NOTES:
    [22.11.2023] pzotov
    1. Parameter ReadConsistency in firebird.conf must be set to 0, i.e. NOT-default value.
    2. TIL = "RC NO_record_version" can be used to check feature since gh-7811 was fixed (20.11.2023 in master)
    3. Only persistent table is checked. For session-level GTT (using two transactions for single attach)
       it is unable to run 'select ... with lock' or 'update/delete ... skip locked': exception raises with message
       "SQLSTATE = HY000 / Cannot select temporary table ... WITH LOCK"
       Discussed with dimitr and hvlad, 13.09.2023
    4. Added WAIT mode to be checked after fixed https://github.com/FirebirdSQL/firebird/issues/7700
       ( https://github.com/FirebirdSQL/firebird/commit/5b14baa37b6ee214cd8ccc21f2e99dce119fe60e )
       NOTE: before fix gh-7700, following statement hanged:
         set transaction read committed record_version WAIT;
         select id from test order by id with lock skip locked
    5. Here we check only 'SELECT ... WITH LOCK' behavour. Results of UPDATE and DELETE are checked in gh_7810_test.py

    [25.11.2023] pzotov
    Writing code requires more care since 6.0.0.150: ISQL does not allow to specify THE SAME terminator twice,
    i.e.
    set term @; select 1 from rdb$database @ set term @; - will not compile ("Unexpected end of command" raises).

    Checked on 6.0.0.137 (SS/CS), 5.0.0.1274 (SS/CS).
