Log: Bug #51691 (Unnecessary realloc causes crashes in PHP trunk tests
with interned strings).  Updated tests check some other edge cases

------------------------------------------------------------------------

Description:
------------
These OCI8 tests are crashing after the implementation of "interned

string" in the PHP trunk code:



bind_char_1.phpt

bind_char_2.phpt

bind_char_3.phpt

bind_char_4.phpt

bind_rowid.phpt

error_bind.phpt



This is due to a realloc in php_oci_bind_post_exec() to add a null

terminator for bound data.  The crash happens on IN binds that are

interned since realloc is not permitted for interned strings.  Because

string IN binds are always null terminated the realloc is unnecessary.

Null strings are apparently not interned so modification of their zval

to force an empty string is OK.



String OUT binds have new memory allocated in php_oci_bind_callback()

and are not interned so they can be realloced.  Also all current test

cases already get null terminated output from Oracle.
