* Extensible split data sync capability through transactions. - Split common transport has been split up between the transport layer and data layer. - Split "transactions" model used, with convergence between I2C and serial data definitions. - Slave matrix "generation count" is used to determine if the full slave matrix needs to be retrieved. - Encoders get the same "generation count" treatment. - All other blocks of data are synchronised when a change is detected. - All transmissions have a globally-configurable deadline before a transmission is forced (`FORCED_SYNC_THROTTLE_MS`, default 100ms). - Added atomicity for all core-synced data, preventing partial updates - Added retries to AVR i2c_master's i2c_start, to minimise the number of failed transactions when interrupts are disabled on the slave due to atomicity checks. - Some keyboards have had slight modifications made in order to ensure that they still build due to firmware size restrictions. * Fixup LED_MATRIX compile. * Parameterise ERROR_DISCONNECT_COUNT.
