[VOTE] Namespaced in bundled extensions

Hi internals,

I've opened the vote on
https://wiki.php.net/rfc/namespaces_in_bundled_extensions. Voting will
close 2021-05-03.

Please see https://externals.io/message/113270 and
https://externals.io/message/113960 for discussions relating to this RFC.

This RFC has been accepted, with 37 votes in favor and one against.

Based on this policy, we plan to namespace a few class additions that are
part of the resource to object migration, and have been added (or will be
added) in PHP 8.1:

• IMAPConnection -> IMAP\Connection
• FTPConnection -> FTP\Connection
• LDAP -> LDAP\Connection
• LDAPResult -> LDAP\Result
• LDAPResultEntry -> LDAP\ResultEntry
• PgSql -> PgSql\Connection
• PgSqlResult -> PgSql\Result
• PgSqlLob -> PgSql\Lob

Regards,
Nikita
