care has to be taken when splitting the host into SERVER_NAME and SERVER_PORT,
as ipv6 uses : in the host part. also do it consistently, the host can be set
thru the request uri and the host header.
set REMOTE_USER to empty string to prevent accidents.
we do not handle chunked transfer encoding, just assuming the client doesnt
do keep alive is wrong. we have to reject the post when the client tries
chunked post with 411 "Length required" error.
The mode printed under the -l option contains 11 characters,
interpreted as follows: the first character is
d if the entry is a directory;
a if the entry is an append-only file;
- if the entry is a plain file.
Therefore, handle them in automatically generated directory listings.
apache sends Content-Encoding: gzip header for Content-Type: application/x-gzip
causing hget to decompress tgz files.
from the w3c:
The Content-Encoding entity-header field is used as a modifier to the media-type.
When presented, its value indicates what additional content codings have been applied
to the entity-body, and thus what decoding mechanisms must be applied in order to
obtail the media-type referenced by the Conent-Type header field. Content-Encoding
is primarily used to allow a document to be compressed without losing the
identity of its underlying media type.
this is clearly silly, as the file is already compressed, and decompressing it
will not yield the indicated Content-type: application/x-gzip, but a tarball.

previously ircrc dialed through /net itself and resolved ips on its own. this prevented the use of an ip address, and also prevented use of ipv6. now you can use an ip, or a dns name that resolves to ipv6. the -T flag is also added to use tlsclient for encrypted connections.
previously, we setup mouse only when vgasize= was specifid in
plan9.ini. with efi systems, the framebuffer is already setup
for us and theres no requirement for going thru aux/vga setup,
but we still want to setup the mouse.
so do the mouseport= check once theres a framebuffer by testing
the existence of '#i/winname' (which fails when thers no
framebuffer).
we used to look for /^Plan 9$/ for the start of kernel
boot messages in /dev/kmesg. but the xen kernel prints
Plan 9 (.....) on boot. so just look for line starting
with /^Plan 9/ for now.
instead of naming devices by ther dynamically assigned device address,
we hash device uniqueue fields from the device descriptor and produce
a 5 digit hex string that will identify the device across machines.
when there is a collision (less than 1% chance with 100 devices),
usbd will append the device address to the name to make it uniqueue
for this machine.
the hname is passed to drivers in the devid argument, which now has
the form addr:hname, where the colon and hname can be omited (for backwards
compatibility).
when the new behaviour isnt desired, nousbhname= environment variable
can be defined giving the old behaviour.
