meson: use .require() and .disable_auto_if() method for features
The method is now in 0.59, using it simplifies some conditionals.
There is a small change, which is to build virtfs-proxy-helper in a
tools-only build. This is done for consistency with other tools,
which are not culled by the absence of system emulator binaries.
.disable_auto_if() would also be useful to check for packages,
for example
-linux_io_uring = not_found
-if not get_option('linux_io_uring').auto() or have_block
- linux_io_uring = dependency('liburing', required: get_option('linux_io_uring'),
- method: 'pkg-config', kwargs: static_kwargs)
-endif
+linux_io_uring = dependency('liburing',
+ required: get_option('linux_io_uring').disable_auto_if(not have_block),
+ method: 'pkg-config', kwargs: static_kwargs)
This change however is much larger and I am not sure about the improved
readability, so I am not performing it right now.
