Fixes reading EMBL sizes in some files and makes this function readable
while at it.
Would be good to inline mp_log2(), but should be good enough.
Fixes: #15691
This allows to select DVD/Blu-Ray title easily. Titles are listed as
editions with their duration and number.
I wanted to include Angles also in this selection, but currently Angles
are not that well supported, so let's stick with titles and leave the
rest for the future changes.
We might migrate to lavf demuxer for DVD/Blu-Ray in the future, the mpv
implementation is rotted anyway.
Fixes#14586
Also rename the field to appropriately reflect what it is supposed to be
used for. The only other use of this was to search for ordered chapter
sources, and that makes no sense for mkv files from stdin.
This also fixes autocreate-playlist loading in the current directory
when the input file is stdin.
The naming of these conflict with existing mpv protocols, so skip if we
get them. Users can still use them via lavf://bluray: or lavf://dvd: if
they wish.
Previously, all stream protocols were a static list in mpv. This is okay
for own builtin stuff, but for protocols that depend on ffmpeg it's not
so great. Support for certain protocols may or may not be enabled in a
user's ffmpeg and the protocol list that mpv generates should ideally
match this. Fix this by implementing a get_protocols method for
stream_lavf that will have different results depending on the ffmpeg mpv
is built against. We keep the safe and unsafe protocols separation. The
former is essentially a whitelist. Any protocol that is found in ffmpeg
but is not in the safe whitelist is considered unsafe. In the stream
list, ffmpeg is moved to the bottom so any possible protocols that are
added in the future don't automatically take precedence over any builtin
mpv ones.
Reading an entire file is a common operation, meanwhile
stream_file will happily open a directory. This doesn't match well.
Analogously for open_output_stream().
The stream layer is just not the right place to make this change
since it's also used for completely unrelated purposes such as reading
configs.
This reverts commit bb7a485c09.
```
dd if=/dev/zero of=/tmp/10g.empty bs=1 seek=10G count=0
dd if=/dev/zero of=/tmp/10m.empty bs=1 seek=10M count=0
time mpv /tmp/10{g,m}.empty
```
I keep files with the name format `${name}-${hash}.${ext}.empty`
around, where the original is removed, and a sparse file with
the size of the original is created instead.
A lot of time is wasted on such files when going through
playlists/directories that include some of them.
This admittedly may not be that common of a use-case.

This is useful e.g. when the caller dup2's a socket into stdin, or
passes a socket/pipe as /dev/fd/{fd}, because it is impossible to seek
on sockets and pipes.
- Don't define _GNU_SOURCE on Windows, no need
- Define WIN32_LEAN_AND_MEAN to strip some unneded headers from
windows.h
- Define NOMINMAX and _USE_MATH_DEFINES as they are common for Windows
headers
