Fixup catchall_info to return iterator, not self

Correct syntax errors

Teach CLI about catchall* commands

Provide catchall_* methods to the Handler class

First version of a CatchallAlias class I based the CatchallAlias class in catchall.py heavily on the Alias class, but by copy, not deriving. The two are functionally related, but the implementations are too different because CatchallAliases have no localpart.

Add database table for catchall destinations Catch-all aliases are stored for a domain. Since there can be multiple destinations per domain, this is done using a 1:n relation on the gid. This commit extends the SQL schema definition and also provides appropriate upgrade DDL.

pgsql: Merged types and functions into the create_tables… files.

postfix: Removed VIEW-based comments from configuration files.

pgsql: Removed most of the VIEWs. There are only two views left for now: - postfix_gid - vmm_domain_info All other views have a faster replacement: plpgsql functions.

Ignore even more Debian-build-related files

Ignore more Debian-build-related files Debian produces log and debhelper files in debian/* that do not need to be known to mercurial. Hence, this patch adds the globs to .hgignore.

Add non-root TODO

VMM/config: Fixed a typo: s/DB_MUDULES/DB_MODULES/g.

Ignore build files related to Debian packaging During Debian packaging, the package is built in ./debian/vmm/, and quilt is used (./.pc/). Both directories contain only generated files and should hence be ignored from the perspective of Mercurial.

Instruct mercurial to ignore build directory Python's distutil builds the package into ./build/, which can and should be ignored with respect to the repository. This patch simply adds the appropriate line to .hgignore.
