Dmitry Frank 23122b327c Remove old docs, rename docs_new to docs
It would be probably good idea to also remove tools/docgen.py and
asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which
may contain some useful info which we'll need at least to review before
removing.

Fetch an HTTP form variable.
Fetch a variable `name` from a `buf` into a buffer specified by
`dst`, `dst_len`. Destination is always zero-terminated. Return length
of a fetched variable. If not found, 0 is returned. `buf` must be
valid url-encoded buffer. If destination is too small, `-1` is returned.
