Deleting unnecessary files from ADOdb

Bug 1672867

On the principle that it's good secur1ty to remove executables you're not likely
to use, clearing out all the bits of ADOdb we're currently not using. This includes
drivers and data dictionaries for other DBs, tests, docs, icons, PHP4 session code,
pear auth container, and non-English error messages.

Check for valid columns in adodb postgres64 driver MetaIndexes fn

Bug 1672867

Indexes on functions of columns have a 0 in the indkey column of
pg_catalog.pg_index, which doesn't refer to a column.

Don't return any columns for the index, rather than returning an empty
column name.

ADODB modification: add __wakeup to connection object

Bug 1672867

This reconnects to the db after wakeup, as resource types cannot be
serialized and unserialized.

This is necessary for unit tests, phpunit backups and restore globals
between each test.
