flac_read_timestamp() applied av_init_packet() to a packet (which
initializes all fields of the packet except for data and size) and then
went on to use only the data and size fields. In other words: Said
packet can be removed and replaced by an uint8_t * and an int.

The current approach has two different calls to av_bsf_send_packet():
A normal one, sending a packet; and an extraordinary one just for
flushing. These can be unified into one by making use of the newly
documented fact that av_bsf_send_packet() allows to signal flushing via
empty packets (i.e. packets without data and side-data).
This also fixes CID 1455685 which resulted from the fact that the call
for flushing was not checked given that it couldn't fail.

mp3 header bitstream syntax:
header()
{
syncword 12bits bslsf
id 1bit bslsf
layer 2bit bslsf
protection_bit 1bit bslsf
bitrate_index 4bits bslsf
sampling_frequency 2bits bslsf
padding_bit 1bit bslsf
private_bit 1bit bslsf
mode 2bits bslsf
mode_extension 2bits bslsf
copyright 1bit bslsf
original/home 1bit bslsf
emphasis 2bits bslsf
}
if the header is masking with MP3_MASK(0xFFFE0CCF), below fields will be cleared:
protection_bit, bitrate_index, sampling_freqency, mode
with SAME_HEADER_MASK(0xFFFE0C00), extra below fields will be cleared which didn't make
sense:
mode_extension, copyright, original/home, emphasis
As the MP3_MASK is good for same mp3 header masking and is defined in the
header, so it's preferable to remove SAME_HEADER_MASK to keep the masking same.

This compared to the other suggestions is cleaner and easier to understand
keeping the condition in the if() simple.
This affects alot of fate tests.

This introduces two new AVOption options for the FTP protocol,
one named ftp-user to supply the username to be used for auth,
one named ftp-password to supply the password to be used for auth.
These are useful for when an API user does not wish to deal with
URL manipulation and percent encoding.
Setting them while also having credentials in the URL will use the
credentials from the URL. The rationale for this is that credentials
embedded in the URL are probably more specific to what the user is
trying to do than anything set by some API user.

A too big picture will case the muxer to write a truncated block size (uint24)
causing the output file to be corrupt.
How to reproduce:
Write a file with truncated block size:
ffmpeg -y -f lavfi -i sine -f lavfi -i color=red:size=2400x2400 -map 0🅰️0 -map 1✌️0 -c✌️0 bmp -disposition:1 attached_pic -t 1 test.flac
Try to decode:
ffmpeg -i test.flac test.wav
