bbf483f855 Change the name of the _texte64() interfaces to just _test64(), without the "e".

da4ca9d19c Add new APIs that take 64-bit length parameters: 
sqlite3_malloc64(),
sqlite3_realloc64(),
sqlite3_bind_blob64(),
sqlite3_bind_texte64(),
sqlite3_result_blob64(),
and sqlite3_result_texte64().
Internal memory allocation routines also now use 64-bit unsigned length
parameters for safety.
Also add the sqlite3_msize() interface.
Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a
integer overflow problem.

86a1119133 Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL 
second argument.  Doing so is harmless when N==0, but it causes an assert()
to fail that was placed to quiet static analyzers.
