[pve-devel] [PATCH proxmox-widget-toolkit 1/2] FileBrowser: allow downloading root folder and simplify code

Smoke tested by downloading an entire container archive as zip, extracting and
checking the files. If there was a reason for this to be disabled let me know.

Based on my previous series to move the FileBrowser to the widget toolkit:
https://lists.proxmox.com/pipermail/pbs-devel/2021-April/002590.html

Depends on the proxmox-backup patch to work correctly.

[pve-devel] [PATCH proxmox-backup 2/2] api/datastore: allow pxar file download of entire archive

[Stefan Reiter]

Treat filepaths like "/root.pxar.didx" without a trailing slash as
wanting to download the entire archive content instead of erroring. The
zip-creation code already works fine for this scenario.

applied, thanks!

But that API is definitively weird in general...

1. old style API definition, should use the #[api()] macro instead
2. perly "params: Value", yeah, no thanks.
3. hard coded return stream type, one should be able to download also a single
   file as zip, and we knew that we wanted .tar then too, so not providing an
   param for that is weird.
4. accessed via /json/ path but never returns json

just fyi

the api macro cannot handle AsyncHttp api calls (yet?), but this is 
required for the stream

a result from above, without api macro no de-structuring of parameters

we always can add as much, but until now, generating a zip for a single
file was not really sensible

> 4. accessed via /json/ path but never returns json

all api calls need a formatter to call, should we add a
new one for download type?

that shoudn't be a hard problem, it's a macro it can expand to whatever..

see above

Compression isn't the only benefit a encapsulation like an archive format.

I know that all paths have a formatter, does not validates misusing JSON
for something completely different ;)

Added a actual config sections with comments for the widget specific params.
