Ryan Houdek a1ed54adc7 FEXRootFSFetcher: Add support for EroFS
Fixes a bug in `ExecAndWaitForResponse` where results > 1024 bytes would
overwrite data.

Switches from a custom format txt file to a json file.
JSON file now has a "Type" field to specify squashfs versus erofs.

JSON is now versioned so we don't need to move the file around, just
append to a new versioned segment.

Only shows erofs files if you have the bleeding edge `erofsfuse`
application.
This application was available starting with erofs-utils v1.5 which was
released on 2022-06-13, so it isn't available pretty much everywhere.

Ryan Houdek bc2840e4a7 FEXRootFSFetcher: Update and fix xxhash file hashing
The final tail of the file reading was incorrect, so our hashing was
"correct" but it was using stale data from the previous block size read.

Noticed this while wiring up the CI rootfs fetching since the hashing is
a lot simpler there.

Now instead of reading a tail, just attempt to read the full block size
and use the resulting data size instead. Confirmed it matches expected
results now.

In the process we are going to need to update hyperlinks and hashes
anyway, change the hash to XXH3 so it is faster to run.

The Hypnotron 17e5d73e64 Fix dangling curl hyphen
Fixes a regression in fa87c73b9ee60a334eace2cdc3097725cbaf5b88; curl complains "curl: option -: is unknown" when trying to fetch a RootFS without this.

Ryan Houdek eaa75c1ed2 FEXRootFSFetcher: Don't continue download
While our CDN supports download continue, the backblaze storage backing
does not.

Ryan Houdek ee04067424 FEXRootFSFetcher: Fixes some edge case behaviours
Makes curl do its continue feature to give the users the best chance of
downloading a rootfs. We don't need to restart the full file transfer on
failure. Helps people with slower connections.

On failure to download, asks the user if they want to retry the download
rather than just exiting with a weird error about hash failure.

Once the image is downloaded, now changes options depending on if
squashfuse or unsquashfs works.

Prevents the user from selecting a bad option and getting unexpected
behaviour. Ideally we would do a squashfs mount test as well for
platforms that don't have working FUSE, like termux. This is harder to
get right and its for an unsupported platform, so I'm not going to
invest more time with it.

Ryan Houdek e4aef26ef5 FEXRootFSFetcher: Adds helper namespace for tool checking
Location to check if curl, squashfuse, and unsquashfs are working.

unsquashfs is a bit more complex where it needs to parse the help output
to see if zstd is supported

Ryan Houdek a41dc8eafa FEXRootFSFetcher: Fix pipe redirecting
In the case of launching without stdout/stderr then redirection could
have these constants be a redirected FD that sits in the same fd number.

Use -2 to indicate no redirection.
Use -1 to indicate closing traditional stderr/stdout
The rest will indicate if stdout and stderr should be replaced as
normal.
Making sure not to close the incoming fds if they matched the
stdout/stderr FD numbers.

Ryan Houdek 5a5a498ed6 FEXRootFSFetcher: Check if curl is installed and fail before running
Before doing anything that requires curl, actually check if it is
installed.
Then instruct the user to install curl before using.

Doesn't try installing curl itself since we don't have a clean way to
execute sudo from potentially GUI.

Fixes #1498

Ryan Houdek 285ed8f1e0 FEXRootFSFetcher: Adds new Exec function with stdout,stderr redirection

Ryan Houdek a68da468a5 FEXRootFSFetcher: ExecAndWaitForResponse sign extend program result
Only the lower 8bits of the execve result is the program result.
Makes sure to sign extend it so -1 is a true -1 instead of 255

Ryan Houdek 9eca823e84 Stop hardcoding /usr/bin paths
Instead of using execve, use execvpe.
This glibc helper will search PATH or `confstr(_CS_PATH)`

Ryan Houdek 9c49bd3c8e FEXRootFSFetcher: Remove 0x prefix on hash
So as to not confuse users who just copy and paste the hash without
thinking

Ryan Houdek 2c31080fd4 FEXRootFSFetcher: Adds a new tool to help set up a new RootFS
This tool supports both a zenity and tty interface.
TTY will be presented if available while Zenity will be used otherwise.

This tool pulls a rootfs list from https://rootfs.fex-emu.org/
It then allows you to select a rootfs from the list, download it, place
it in to the correct working folder, extract it if desired, and set it
as the current default RootFS.

This requires curl and potentially zenity installed to use.
Maybe also unsquashfs if the user chooses to extract the image.

This is an all in one tool to quickly get a new user up and running.

Additionally if you pass in a file path in to the tool, it will generate
an xxhash of the file and exit out. This is the hash used to ensure the
files are valid.
