bpo-44329: Refactor sqlite3 statement creation (GH-26566)
Call SQLite API's first, and return early in case of error. At the end,
allocate the object and initialise members. We now avoid unneeded
alloc/dealloc's in case the statement creation fails.

bpo-42972: Track sqlite3 statement objects (GH-26475)
Allocate and track statement objects in pysqlite_statement_create.

By allocating and tracking creation of statement object in
pysqlite_statement_create(), the caller does not need to worry about GC
syncronization, and eliminates the possibility of getting a badly
created object. All related fault handling is moved to
pysqlite_statement_create().

This is based on

though we can be a bit more aggressive about deleting code.

  Fixes issue #3103. In the sqlite3 module, made one more function static. All renaming public symbos now have the pysqlite prefix to avoid name clashes. This at least once created problems where the same symbol name appeared somewhere in Apache and the sqlite3 module was used from mod_python.
