0a025aabfd add support for Git over SSH
We use the system commands "git-receive-pack", "git-upload-pack" and
"git-upload-archive". they need to be installed and in your system's
PATH. Since we execute system commands we have no direct control on
file creation/deletion and so quota check is suboptimal: if quota is
enabled, the number of files is checked at the command begin and not
while new files are created.
The allowed size is calculated as the difference between the max quota
and the used one. The command is aborted if it uploads more bytes than
the remaining allowed size calculated at the command start. Quotas are
recalculated at the command end with a full home directory scan, this
could be heavy for big directories.

9c4dbbc3f8 sftpd: add support for some SSH commands

if the matching system commands are not available, for example on Windows

871e2ccbbf sftpd: refactor connection closing
we have not known bugs with the previous implementation anyway this one
is cleaner: the underlying network connection is directly related with
SFTP/SCP connections.

1d917561fe sftpd: add support for upload resume
we support resume only if the client sets the correct offset while resuming
the upload.
Based on the specs the offset is optional for resume, but all the tested
clients sets a right offset.
If an invalid offset is given we interrupt the transfer with the error
"Invalid write offset ..."

See https://github.com/pkg/sftp/issues/295

This commit add a new upload mode: "atomic with resume support", this acts
as atomic but if there is an upload error the temporary file is renamed
to the requested path and not deleted, this way a client can reconnect
and resume the upload
