etc.curl: Formal review begin

[Johannes Pfau]

Damn, I forgot the most important part:

etc.curl currently uses none of D's "advanced" function attributes.
This means that etc.curl can't be used in safeD for example. IMHO
that's a big problem: New phobos code should be usable in safeD it's
bad enough that lots of old code isn't.

So:
@safe or @trusted needs to be added to almost all functions in etc.curl.

'const' (as in const functions, not const arguments) probably doesn't
make sense for a wrapper, so that's not needed.

There are some functions which could be 'pure': escape & unescape for
example

Seems like most functions can throw, but maybe some are 'nothrow'.
