libgpiod: Add Rust bindings

Hello, Here is another version of rust bindings for libgpiod v2.0, based of the next/libgpiod-2.0 + the HTE patch from Bartosz [1]. Pushed here: https://github.com/vireshk/libgpiod master [I have pushed v5 and v4 there too, in case someone wants to look at the changes]. V5->V6: - Updates according to the new line-settings interface. - New file, line_settings.rs. - Renamed 'enum Setting' as 'SettingVal' to avoid conflicting names, as we also have 'struct Settings' now. - Support for HTE clock type. - Implement 'Eq' for public structure/enums (reported by build). - Remove 'SettingKindMap' and 'SettingMap' as they aren't required anymore. - Updated tests based on new interface. V4->V5: - Arrange as workspace with crates for libgpiod-sys, libgpiod, gpiosim. - Use static libgpiod and libgpiosim libraries instead of rebuilding again. - Arrange in modules instead of flattened approach. - New enums like Setting and SettingKind and new types based on them SettingMap and SettingKindMap. - New property independent helpers for line_config, like set_prop_default(). - Improved tests/examples, new example for gpiowatch. - Add pre-built bindings for gpiosim too. - Many other changes. V3->V4: - Rebased on top of new changes, and made changes accordingly. - Added rust integration tests with gpiosim. - Found a kernel bug with tests, sent a patch for that to LKML. V2->V3: - Remove naming redundancy, users just need to do this now use libgpiod:{Chip, Direction, LineConfig} now (Bartosz); - Fix lifetime issues between event-buffer and edge-event modules, the event buffer is released after the last edge-event reference is dropped (Bartosz). - Allow edge-event to be copied, and freed later (Bartosz). - Add two separate rust crates, sys and wrapper (Gerard). - Null-terminate the strings passed to libgpiod (Wedson). - Drop unnecessary checks to validate string returned from chip:name/label/path. - Fix SAFETY comments (Wedson). - Drop unnecessary clone() instances (Bartosz). V1->V2: - Added examples (I tested everything except gpiomon.rs, didn't have right hardware/mock device to test). - Build rust bindings as part of Make, update documentation.
