Subject: [PATCH] httpd: keep the send_l2 flags in bit memory

The two flags added with the JSON fix sit in data, where internal RAM is
full enough that this branch stopped linking for some toolchains. __bit
puts them in the bit area instead and hands three bytes back to the
stack: SSEG goes from 131 to 134 on SWTGW218AS.

Patch by vDorst on the pull request.
