ftp: simplify socket buffer handling to improve performance

Only set the socket buffer sizes if the user explicitly sets the
rcvbuf (SO_RCVBUF) or sndbuf (SO_SNDBUF) to a positive value.

Otherwise leave to the operating system default.

Determine the transfer size based on the socket buffer size
clamped to 1 KiB .. 128 KiB, using using the maximum (128 KiB)
if the socket buffer size is 0 (autodetect).

Improves transfer performance on long fat links.

Bump version to 20260207.
