Bug#952942: biglybt: package ignores ~/.biglybt/java.vmoptions

[elde at i2pmail.org]

Package: biglybt
Version: 2.2.0.2-2


Upstream version of BiglyBT uses options specified in `~/.biglybt/java.vmoptions` (one per line) to apply them to the JVM.

It's useful, since it allows to allocate more memory than the default, or run with some nonstandard options. In my case, without allocating more memory than the default for JVM is in Debian, I'm running into performance issues.

Example content of `java.vmoptions` file:

```
-Xmx1024m
-Xms256m
-XX:+PerfDisableSharedMem
-XX:+UnlockExperimentalVMOptions
-XX:+UseZGC
```

Additionally, upstream version of BBT provides information about the file and what options are specified in it in its options (Tools > Options > Startup & Shutdown), and it also has GUI for setting how much memory is JVM allowed to use.

Currently I worked around this issue by putting together content of `/usr/bin/biglybt` and options from the ignored file in a custom script.

By the way, `$@` in `/usr/bin/biglybt` should be enclosed in double quotes, otherwise the wrapper is going to treat spaces in torrent filenames as arg separator, preventing it from being able to open torrents with spaces in filename.

Feel free to use the patch:
