sasl: binary messages

[monnerat]

Capabilities of sasl module are extended to exchange messages in binary as an alternative to base64.

If http authentication flags have been set, those are used as sasl default preferred mechanisms.

Why this change? We cannot assume that a long is larger than 32 bit anyway... and if you want to store 32 bit, why use 64 bit on some platforms?

[monnerat]

HTTP authentication flags are already defined as unsigned long: although not yet related, the idea behind this change is to ease a possible future unification of sasl and http authentication flags.
This is the only reason. But perhaps the change would have to be done the other way on http side, which is not the target of my current work.
I can drop it for now, if you prefer.

IMHO, this is ready for review/pull.

@bagder : Please can you look at this while the feature window is open? Having it unpushed blocks my work on openldap. Thanks.

@monnerat for the future, please request a review of the PR. It's an excellent way to signal that you're ready/done (and a good way for me to spot/filter such PRs).

Sorry for using a comment for that, but the "request review" icon is sometimes missing. Github bug ?
Anyway I'll use it when present.

Thanks!

Thanks to you for pulling.
