doc/t2h.pm: fix missing TOC with texinfo 6.8 and above
Since texinfo 6.8, there's no longer an INLINE_CONTENTS variable.

makeinfo: warning: set_from_init_file: unknown variable INLINE_CONTENTS

texinfo commit 62a6adfb33b006e187483779974bbd45f0f782b1 replaced
INLINE_CONTENTS with OUTPUT_CONTENTS_LOCATION.

texinfo commit 41f8ed4eb42bf6daa7df7007afd946875597452d replaced
OUTPUT_CONTENTS_LOCATION with CONTENTS_OUTPUT_LOCATION.

With texinfo 6.8 and above, the same as INLINE_CONTENTS=1 could be
achieved by CONTENTS_OUTPUT_LOCATION=inline.

doc/t2h.pm: fix missing CSS with texinfo 6.8 and above
Since texinfo commit 6a5ceab6a48a4f052baad9f3474d741428409fd7, the
formatting functions, in particular begin_file, program_string and
end_file, are prefixed with format_, i.e. format_begin_file, etc.

This patch fixes building the documentation when texinfo 6.8, or
above, is used:

Unknown formatting type begin_file
 at /usr/bin/makeinfo line 415.
Unknown formatting type program_string
 at /usr/bin/makeinfo line 415.
Unknown formatting type end_file
 at /usr/bin/makeinfo line 415.

avformat/hls: reduce default max reload to 3
The 1000 did result in the appearance of a never ending reload loop

The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"

Trying to reload 3 times seems a better default than 1000 given these
durations
