3220a894f7 http: add hack to make streams served by MediaGateway not seekable
These streams are reported as seekable, but all tests show they are not,
and the server merely pretends the streams are seekable. The server
responds with:

    content-range: bytes 0-1999999999/2000000000

Range requests seem to be correctly answered, but the actual data
returned at the same offset is different. Assume this is a bug in the
server software. The server identifies itself as:

    Server: MediaGateway 3.5.2-001

Add a hack that checks the server name, and disables seeking in this
case.

5970f4bb02 avformat/http: check the auth string contents not the pointer which cannot be NULL
It appears this bug originates from a "work in progress" patch from
ffmpeg-devel that was heavily redesigned by and integrated in libav

And that patch even had a reply and review on the mailing list pointing
out that it had a bug.

This fixes a deadlock with ffserver

See: [FFmpeg-devel] [PATCH] Fix HTTP authentication problem for POST actions.
     [FFmpeg-devel] [PATCH 1/3] Introduce auth_phase flag, which will be true if authorization needs to be sent, but the type of authorization is not known yet Partial fix #3036

71549a857b http: Support auth method detection for POST
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.

eb8b05a382 http: Add an option for forcing basic authentication
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.

a92fbe16f2 lavf/http: add support for reading streamcast metadata
Allow applications to request reading streamcast metadata. This uses
AVOptions as API, and requires the application to explicitly request
and read metadata. Metadata can be updated mid-stream; if an
application is interested in that, it has to poll for the data by
reading the "icy_metadata_packet" option in regular intervals.

There doesn't seem to be a nice way to transfer the metadata in a nicer
way. Converting the metadata to ID3v2 tags might be a nice idea, but
the libavformat mp3 demuxer doesn't seem to read these tags mid-stream,
and even then we couldn't guarantee that tags are not inserted in the
middle of mp3 packet data.

This commit provides the minimum to enable applications to retrieve
this information at all.

de9cd1b173 lavf: Handle the environment variable no_proxy more properly
The handling of the environment variable no_proxy, present since
one of the initial commits (de6d9b6404), is inconsistent with
how many other applications and libraries interpret this
variable. Its bare presence does not indicate that the use of
proxies should be skipped, but it is some sort of pattern for
hosts that does not need using a proxy (e.g. for a local network).

As investigated by Rudolf Polzer, different libraries handle this
in different ways, some supporting IP address masks, some supporting
arbitrary globbing using *, some just checking that the pattern matches
the end of the hostname without regard for whether it actually is
the right domain or a domain that ends in the same string.

This simple logic should be pretty similar to the logic used by
lynx and curl.
