main.c: In function 'readline_into_buffer':
main.c:927: warning: unused variable 'p_buf'

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Add new function readline_into_buffer() that allows the
output of readline to be put into a pointer to char buffer.

This refactoring allows other functions besides the
main command loop to also use the same input mechanism.

Fixed some broken instances of "#ifdef CMD_CFG_IDE" too.
Those always evaluated TRUE, and thus were always compiled
even when IDE really wasn't defined/wanted.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
