Adds a new function gdb_bin2hex() to convert binary into hexadecimal string representation. This is similar to bin2hex() but does not force a null character at the end of the output buffer. This avoids an issue where the last character of the hexadecimal string is replaced with null character before sending to GDB. Signed-off-by: Daniel Leung <daniel.leung@intel.com>
