* libchip/network/i82586.c: Readdress use of ctype methods per
recommendation from D.J. Delorie on the newlib mailing list. We
should pass an unsigned char into these methods.

* start/start.S: Micromon on bf537 uses DMA for UART reception.
This prevents the UART driver in RTEMS from working (and also
causes received characters to be stored in a buffer that RTEMS
doesn't know about, so it's potentially dangerous, but in practice
the risk is small since an RTEMS app intended to be booted from
Micromon would normally be configured to leave the RAM Micromon
uses reserved). The attached patch corrects this by disabling
all DMA channels at startup.
* network/if_mve/mv643xx_eth.c: Fixed alignment attribute
in descriptor declaration. Not the pointers to the descriptors
have to be aligned but the descriptors themselves (didn't
cause problems but caused unnecessary holes in 'private' struct).
FIX: Added more robustness when number of available TX descriptors
drops to zero. (This can e.g., happen if the link goes bad causing
packets to stall in the FIFO.) At the following points the transmitter
is explicitly (re-)started:
o when link comes up and number of available TXDs is zero the
TX is restarted.
o on a failed attempt to send data due to lack of TXDs the
TX is restarted if swiping the TX ring doesn't yield any
buffers (i.e., if the # of available buffers is still zero
after the swipe).
