qapi: Clean up cgen() and mcgen()
Commit 05dfb26 added eatspace stripping to mcgen(). Move it to
cgen(), just in case somebody gets tempted to use cgen() directly
instead of via mcgen().
cgen() indents blank lines. No such lines get generated right now,
but fix it anyway.
We use triple-quoted strings for program text, like this:
'''
Program text
any number of lines
'''
Keeps the program text relatively readable, but puts an extra newline
at either end. mcgen() "fixes" that by dropping the first and last
line outright. Drop only the newlines.
This unmasks a bug in qapi-commands.py: four quotes instead of three.
Fix it up.
Output doesn't change
