timer: fix documentation errors
eui64: fix spelling error
eui64: add parsing and as-text capabilities
uptime: support delay macro based on utt as well as ms
trxeb: correct LED sel initialization
timer: lower BSP430_TIMER_ALARM_FUTURE_LIMIT

This is intended to address issues where the clock increments during the set
operation; 2 ticks is adequate for this, and 5 is so long it inhibits useful
32 kiHz delays.
eui64: support application-specific, platform-specific, or generic

configBSP430_EUI64_USE_PLATFORM is intended to specify use of the
platform-provided EUI64 routine (as opposed to one provided by the
application), and did not adequately distinguish the case where the platform
has a custom implementation.  Now that there are other functions in the
utility/eui64 module that distinction is important.
