- lua parsing: lparser.c was modified to allocate some of its structures to the heap instead of the stack. Also, the stack size was bumped to at least 2048 bytes on all backends. Hopefully this will take care of most issues related to stack overflows. - new buffering system available. Originally I planned to make it fully generic, but I came to the conclusions that this would take too much development work and system resources (RAM/Flash) if done properly, so currently it's only used on UART RX (although it could be easily extended for other peripherals). For an example of use check the AT91SAM7X and AVR32 backend (platform_init and associated interrupt handlers and also platform_conf.h). - new XMODEM implementation. Better, cleaner, bug fixed, and BSD instead of GPL. - AVR32 can use the huge (32MBytes) SDRAM on the board as system memory now. - fixed an error in elua_sbrk/_sbrk_r (and revised the compilation options for dlmalloc). - added the CPU module and interrupt support on the STR9 platform. - uart module changes: 'sendstr' is out, but the regular 'send' will send strings instead of simple chars (which makes sense since Lua doesn't have a "char" type). Also, the 'timer_id' and 'timout' parameters of the 'recv' function are now optional.

Implementing system timer capabilities - the infinite timeout value is again represented by a special value (not a special timer ID), but this time it's a non-negative value - all timers in the UART module default to the system timer - all timers in the TMR module default to the system timer - implemented a generic system timer mechanism that can be used in conjunction with a timer interrupt. - implemented system timers on LM3S (tested) and STM32 (not tested). Both are based on the Cortex M3 SysTick timer.
