Francisco J. Manno 4398b1f3c1 Fix gcc [-Wsign-compare] warning 
[Warning] mbed_board.c@99,36: comparison between signed and unsigned
integer expressions [-Wsign-compare] is seen during compilation.
Fix the warning and small improvements.

1. Change type of loop variable "i" to the same type as "size".
   Size is > 0 checked by the if statement and i stops at == size
   so none can be negative. However size still needs to be signed
   to detect error codes from vsnprintf.
2. Reduced scope of stdio_out_prev and make sure it's initialized.
3. Define a name for the error buffer size and use vsnprintf instead
   of vsprintf to avoid writing outside of the array.
   NOTE: the if(size > 0) statement doesn't need to change. If
   the message to write is larger than the buffer size vsnprintf
   truncates it automatically but still returns a positive value.
