Pulled in some Unix-specific code from https://github.com/rust-locale/locale_config to reduce dependencies.
First reason to reduce dependencies: gettext-rs is not in Debian. Copying gettext-sys might have made sense, but the interface is somewhat confusing.
For translating a couple identifiers, detection and some hand-rolled hash map is all that is needed, and the option to move to gettext later remains.
locale_config has been stripped of the lazy_static dependency, which, messing with the strtup sequence, might be a source of debugging woes. Plus setting language once in the beginning is somewhat inflexible regarding runtime changes.
Debian uses a separate registry for the packages it distributes. Checksums for some Debian packages don't match anything that's available on crates.io, which is the default source of dependencies. *linked-hash-map* in particular doesn't provide any hash.
As a result, Debian's `Cargo.lock` and crates.io's `Cargo.lock` are not matching, and building is only possible with one or the other, depending on what's checked in.
As a separate issue, Debian packages are usually not checked in in multiple versions, so checking in Debian's `Cargo.lock` would result in the package not building whenever a bugfix is distributed (due to checksum changes).
This change removes the crates.io `Cargo.lock` so that a new one will be created whenever a .deb is built, solving the above. What keeps falsely passing builds from happening is `Cargo.toml` specifying no interface changes, as well as Build-Depends, which seem enough for any other Debian package.
WIP
WIP: keymap generation test passes
meta: Update features and version
WiP: cargo.lock
WIP: don't crash
WIP: no outlines
parsing: New tests
WIP: base level works
WIP: remove old keyboard
symbols correctly input
WIP: lodaing files
WIP: fallback works
Valid fallback
Pros: Ability to use Rust libraries from crates.io
Problems: Need to lock library versions and document their reproducible building, either via Cargo.lock or vendoring.
