Also add support for f64.

You cannot count on it being present on all systems, and you
cannot include libm.h in a host tool, so just hard code a baseline
implementation.

This is so we can sync to x264's version of FMA4 support.

Automatically use VEX-encoding in AVX/AVX2/XOP/FMA3/FMA4
functions for all instructions that exists in a VEX-encoded
version.

This change makes it easier to extend existing code to use AVX2.

Also add support for AVX emulation of a few instructions that
were missing before.

Normally, all channel ids are between 0 and 10, while they in
uncommon cases can have values up to 64k.

This avoids allocating two arrays for up to 64k entries (at a total
of over 6 MB in size) each when most of them aren't used at all.

Inspired by a patch by Jakob van Bethlehem. But instead of doing
an empty POST first to trigger the WWW-Authenticate header (which
would succeed if no auth actually was required), add an Expect:
100-continue header, which is meant to be used exactly for
cases like this.

The header is added if doing a post, and the user has specified
authentication but we don't know the auth method yet.

Not all common HTTP servers support the Expect: 100-continue header,
though, so we only try to use it when it really is needed. The user
can request it to be added for other POST requests as well via
an option - which would allow the caller to know immediately that
the POST has failed (e.g. if no auth was provided but the server
required it, or if the target URL simply doesn't exist).

This is only done for write mode posts (e.g. posts without pre-set
post_data) - for posts with pre-set data, we can just redo the post
if it failed due to 401.

The default is to autodetect the auth method. This does require one
extra request (and also closing and reopening the http connection).
For some cases such as HTTP POST, the autodetection is not handled
properly (yet).

No option is added for digest, since this method requires getting
nonce parameters from the server first and can't be used straight
away like Basic.

Sometimes, if pthread_create() failed, then pthread_cond_wait() could
accidentally be called in the worker threads after the uninit function
had already called pthread_cond_broadcast(), leading to a deadlock.

Don't call pthread_cond_wait() if c->done is set.
