[MINOR] Allow to specify a domain for a cookie

This patch allows to specify a domain used when inserting a cookie
providing a session stickiness. Usefull for example with wildcard domains.

The patch adds one new variable to the struct proxy: cookiedomain.
When set the domain is appended to a Set-Cookie header.

Domain name is validated using the new invalid_domainchar() function.
It is basically invalid_char() limited to [A-Za-z0-9_.-]. Yes, the test
is too trivial and does not cover all wrong situations, but the main
purpose is to detect most common mistakes, not intentional abuses.

The underscore ("_") character is not RFC-valid but as it is
often (mis)used so I decided to allow it.
