rewrite barnard-ui in Python

Browse Source

Replace the shell implementation with Python while keeping the same
dialog-based interface and the same file layout under
~/.config/barnard.
The shell version parsed servers.conf with string operations that lost
whitespace and silently discarded entries it could not read, and every
new feature meant more quoting and subshell handling.

Refuse to start on a servers.conf we cannot interpret.
Unknown keys, stray sections, and invalid ports now name the file and
line instead of being dropped and rewritten over the top of the user's
file. Duplicate server names are reported rather than silently
collapsed.

Keep a backup of the previous server list and flush it to disk.
A save is written to a temporary file, the old one is copied to .bak,
and both the file and its directory are synced before the replace.

Confirm before overwriting or removing a server.

Bracket IPv6 addresses when building the -server argument.
The shell version joined address and port with a colon, which is not a
usable address for an IPv6 literal.

Take the hostname from os.uname rather than the environment.
HOSTNAME is a shell variable and is not exported, so the connect
username lost its host part.
