all: Prune trailing whitespace.

Prune trailing whitespace across the whole project (almost), done
automatically with:

    grep -IUrl --color "[[:blank:]]$" --exclude-dir=.git --exclude=*.exp |\
        xargs sed -i 's/[[:space:]]*$//'

Exceptions:
- Skip third-party code in lib/ and drivers/cc3100/
- Skip generated code in bluetooth_init_cc2564C_1.5.c
- Preserve command output whitespace in docs, eg:
  docs/esp8266/tutorial/repl.rst
