jrohel/NetMount client-v1.5.0,server-v1.4.0 on GitHub

Changes in NetMount server version 1.3.0 -> 1.4.0

Replace err_print and dbg_print with a level-based logger
Previously, there were only two logging levels: dbg_print and err_print.
Additionally, dbg_print had to be enabled at compile time.
Now, both are replaced with a single log() function that supports seven
logging levels: CRITICAL, ERROR, WARNING, NOTICE, INFO, DEBUG, and TRACE.
Users can configure the desired logging verbosity at application startup.
Log messages are written to standard error (stderr) and are automatically prefixed
with ISO 8601 timestamps with millisecond precision.
A new program argument has been added
--log-level=<LEVEL> Logging verbosity level: 0 = OFF, 7 = TRACE (default: 3)
Add support for setting volume label for shared drives
Previously, shared drives had no volume label. Now, the user can specify
a label for each shared drive. If a volume label is not specified,
the default label "NETMOUNT" is used. To share a drive without a volume
label, an empty string can be passed: --label=.
Added optional argument <label>=<volume_label> to the shared drive definition:
<label>=<volume_label> volume label (first 11 chars used,
default: NETMOUNT; use "--label=" to remove)

Don't exit on error in Drive::Item::create_directory_list
If an error occurs during directory listing (e.g. when a request is made
to list a directory using a file-type argument), the error is now only
logged and does not cause the server to exit.
Implement basic INT2F_UNLOCK_FILE handler
Previously, only the INT2F_LOCK_UNLOCK_FILE function (a client request)
was handled. INT2F_UNLOCK_FILE is now supported as well, but both
handlers currently only validate the file handle and log an ERROR if
the handle is invalid. Actual locking/unlocking is not yet implemented
and may be added later.

dump_packet to stderr instead of stdout
server: create_server_path: Add path to exception message
Check if the shared path is a directory
Previously, this check was not performed, so the user could specify
a file (socket, device, ...) instead of a directory as the shared path.
create_directory_list: Add "." and ".." entries only to non-root directories
Previously, "." and ".." entries were added to the list for all directories,
and the find_file function skipped these entries for root directories.

The release includes the complete NetMount source code (server and DOS client) and server builds:

2 builds of server for Windows: for i686 and x86_64 (cross-compiled using MinGW on Linux, tested using Wine on Linux)
4 builds of server for Linux: i686, x86_64, ARM aarch64 big endian, ARM aarch64 little endian (ARM binaries tested using QEMU)

The DOS client has not changed in this release; if needed, use DOS client builds from the older release.
