Changes (C API)

- OCI_Cleanup() now returns FALSE if OCI_Initialize() has not been called
- OCI_GetSQLVerb() handles some new verbs added with Oracle 21c
- OCI_Execute() and related methods return now FALSE and report an OCI_Error for PL/SQL statements raising PL/SQL no_data_found exceptions
    * This revert behavior introduced in v4.3.1 for addressing issue #68
    * Motivation is to re-align on SQL*Plus behavior
- OCI_GetOCIRuntimeVersion() and OCI_GetOCICompileVersion() returned integer values on 6 digits instead of 4 digits
    * Handles now  minor version using 2 digits (e.g. Oracle OCI version 19.16.0)
    * Use macros OCI_VER_MAJ, OCI_VER_MIN, OCI_VER_REV and OCI_VER_MAKE to do computations on versions
- Very old Oracle OCI 8.0.x is now supported 
    - Up to now, OCILIB supported all Oracle versions from 8.1
    - Oracle 8.0 is now also supported for very old legacy systems (as Oracle 8.0 was released in mid 90's)
    - As OCI multi-threaded APIs were only available from 8.1, passing OCI_ENV_THREADED to OCI_Initialize() with Oracle 8.0 will generate an error:
        - OCILIB Error code : OCI_ERR_NOT_AVAILABLE 
        - OCILIB Error message : "Feature not available (Oracle 8.1 multihreading support)"

Fixes (C API)

- Issue 308: OCI_Execute() raises error OCI-22060 when binding host big_int variables with OCI_BDM_OUT in case the SQL or PL/SQL engine sets a NULL value
- Issue 309: OCI_Execute() does not raise exceptions when executing PL/SQL statement raising no data was found PL/SQL exception
- Issue 313: OCI_GetString() returns NULL for CLOB columns is the CLOB row value was filled with empty_clob()
- Issue 314: OCI_BindSetCharsetForm() is not accessible since v4.7.0
- ISsue 316: OCI_DequeueGet() returns messages with OCI_Object payloads that can have NULL properties while being NOT NULL when queued
- ISsue 317: OCI_SubscriptionRegister() generates a segfault on failure
