Add initial FreeBSD support

[CalebHeydon]

This PR adds initial support for FreeBSD (#15309). While there is still work left to be done, it seems to be usable. As discussed by @syobocat (#10247), the changes were just adding target_os = "freebsd" to wherever it checks if the OS is Linux.

Needs to be build with RUSTFLAGS="-C link-dead-code"

Known Issues:

• There's an issue in crates/project/src/environment.rs where a command fails because /bin/sh on FreeBSD doesn't support the -l option.
  
• The file/folder choosers provided by the ashpd crate don't work on FreeBSD (at least with KDE). This isn't that bad since a fallback dialog is used.
  
• Moving to trash won't work.
• Numerous tests fail (when running on FreeBSD). While I haven't looked into this much, it appears that the corresponding features seem to work fine.

Release Notes:

• Added initial support for FreeBSD

Thank you.

This and another place below with Self::Linux looks quite odd, so welcome to fix in in the future PRs.

[CalebHeydon]

Thanks for pointing that out. It probably is correct to set the context to linux, but I'll need to prevent it from setting it to unknown.

• There's an issue in crates/project/src/environment.rs where a command fails because /bin/sh on FreeBSD doesn't support the -l option.

sh -l Option was added to FreeBSD HEAD this week: https://cgit.freebsd.org/src/commit/?id=65f5dd42f11cdcb7716e6cdd09fac2314c144c1f

MFC'ed after a week unfortunately it won't land in the upcoming 14.2-RELEASE. Until then, you can use /usr/local/bin/bash -l.

Hey,
Great job on the PR!
Are there any instructions on how it can be used at this moment ?

Thanks

I had tried building on FreeBSD 15, following these instructions

pkg install -y ca_root_nss protobuf cmake alsa-lib
git clone https://github.com/zed-industries/zed.git && cd zed
export RUSTFLAGS="-C link-dead-code"
cargo build --release

However now it seems to be stuck at missing webrtc deps, what am i missing, i didnt see any mentions of having to install alsa/webrtc

error: failed to run custom build command for `webrtc-sys v0.3.5 (https://github.com/zed-industries/livekit-rust-sdks?rev=060964da10574cd9bf06463a53bf6e0769c5c45e#060964da)`

i don't know if with alsa wrtc works, I'm FreeBSD 14.1 and pulseaudio wrtc-audio (I prefer oss), but I don't know works fine in 15-current. If not works try other old commit.

I'm sorry per my dwm vanilla...

Same root cause of the the issue reported here:

• Can't compile ZED anymore using Vendor - error: failed to run custom build command for `webrtc-sys v0.3.5 #23247

Oddly enough this was not the error i was seeing yesterday and it seemed that commit bf569d7 worked yesterday. However today when i was trying to narrow down what commit broke the current build i started running into the 404 error that you mention.
