* the first one would cause an unnecessary malloc() of iovec storage for
a msg_iovlen of UIO_SMALLIOV although the required amount of memory has
been allocated on the stack.
* the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of
UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.
* availability of POSIX Synchronized I/O (kern.synchronized_io),
* maximum number of iovec structures to be used in readv(2) etc. (kern.iov_max)
via sysctl().
* support $no_proxy, which is a comma or space separated list of
host[:port] elements for which proxying is to be disabled.
(asked for by cgd in [bin/5027])
* if $FTPANONPASS is defined, use that as the anon ftp password
(instead of "`whoami`@")
* allow http URL's without a filename as long as an output file
is specified.
other stuff:
* implement parse_url(), which breaks up a URL into its bits, and use.
* simplify url_get() and auto_fetch() to use parse_url() and to not
modify the supplied URL or a copy of it.
* implement xmalloc() and xstrdup(); error-checked malloc()/strdup()
* add more consistency to messages, quoting strings in output as `%s'
* in the read vnode operator, check for IO_SYNC being set in the ioflag and
synchronously update the file's meta-data if appropriate.
* in the write vnode operator, update the appropriate checks for IO_SYNC being
set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into
IO_SYNC, and require all IO_SYNC bits to be set for operations defined by
synchronized I/O file integrity completion but not by synchronized I/O data
integrity completion.
* if synchronized I/O file integrity completion of read operations was
requested, set IO_SYNC in the ioflag passed to the read vnode operator.
* if synchronized I/O data integrity completion of write operations was
requested, set IO_DSYNC in the ioflag passed to the write vnode operator.
(again); put some constant data into shared structures. This makes it
more look like the mouse part, and it helps USB integration.
Implement wskbd_enable() to enable/disable the keyboard.
