Glenn Strauss 2639e5ae43 [multiple] chunkqueue_write_chunk()
create API in chunk.[ch] for writing a chunk to an fd

(pull similar code from mod_cgi and mod_webdav)

This new API is intended for use on request body input, which is
written to size-limited temporary files controlled by lighttpd and
written to files or pipes.

(network_backend_write() is for writing chunkqueues to sockets)

Glenn Strauss 15bfe5ef0e [mod_webdav] typedef off_t loff_t for FreeBSD
FreeBSD provides an API similar to Linux copy_file_range()
but uses off_t instead of loff_t in the syscall.

off_t is equivalent to off64_t when lighttpd is built with LFS
(and lighttpd is built with LFS enabled by default)

Glenn Strauss 122094e3e3 [multiple] employ http_date.h, sys-time.h

Glenn Strauss 76faed9145 [multiple] replace fall through comment with attr
replace /* fall through */ comment with __attribute_fallthrough__ macro

Note: not adding attribute to code with external origins:
  xxhash.h (algo_xxhash.h)
so to avoid warnings, may need to compile with -Wno-implicit-fallthrough

Glenn Strauss 6bf0b57787 [mod_webdav] unsafe-propfind-follow-symlink option
webdav.opts = ("unsafe-propfind-follow-symlink" => "enable")

This option is unsafe and unsupported.  This option enables non-standard
behavior.  If it works for you, great.  If it does not work for you,
then too bad.

WebDAV resource and collection concepts do not have an equivalence
to unix symlinks.  If "unsafe-propfind-follow-symlink" is "enable",
then lighttpd mod_webdav PROPFIND handling will follow symlinks
if and only if webdav.is_readonly = "enable" is also set.

Allowing symlinks is unsafe in the general case.  Using WebDAV methods
to MOVE a relative symlink does not update the symlink relative target.
LOCK is on the resource (e.g. a symlink), not the target of the symlink.
COPY replaces the resource (e.g. a symlink), not the target of the
symlink.  There are only a few examples of possibly many more reasons
why using symlinks in a WebDAV-writable collection is unsafe.

Glenn Strauss 7c7f8c467c [multiple] split con, request (very large change)
NB: r->tmp_buf == srv->tmp_buf (pointer is copied for quicker access)

NB: request read and write chunkqueues currently point to connection
    chunkqueues; per-request and per-connection chunkqueues are
    not distinct from one another
      con->read_queue  == r->read_queue
      con->write_queue == r->write_queue

NB: in the future, a separate connection config may be needed for
    connection-level module hooks.  Similarly, might need to have
    per-request chunkqueues separate from per-connection chunkqueues.
    Should probably also have a request_reset() which is distinct from
