Change Details

Some hardware/firmware leaves serial console in bogus state before calling user boot code. After that output of `boot2`, `gptboot` and tother second level boot blocks could not be seen by user, which is inconvenient. This diff adds new runtime option `-R`, which force all these boot blocks to send default VT-100 reset command <ESC>c before all output. This sequence could be changed with build time option `BOOT_COMCONSOLE_RESET_TERM_CMD`.
