The eval special builtin now runs the code with EV_EXIT if it was run
with EV_EXIT itself.
In particular, this eliminates one fork when a command substitution contains
an eval command that ends with an external program or a subshell.
This is similar to what r220978 did for functions.
doc/, and now www/ trees, but only using the "cvsup" transport.
When "make update" is run using a tree's makefile, it can also use
"cvs" (except for www/) and "svn" (only src/).
Clean up documentation and code regarding "make update":
- Increase oddness by adding support for WWWSUPFILE and NO_WWWUPDATE to
Makefile.inc1 (analogous to PORTSSUPFILE/NO_PORTSUPDATE and
DOCSUPFILE/NO_DOCUPDATE; WWWSUPFILE already supported by www/Makefile).
- Document all trees that support CVS_UPDATE.
- Document all trees that support SUP_UPDATE.
- Document SVN_UPDATE.
- Document NO_WWWUPDATE.
- make.conf(5) mistakenly said that *SUPFILE* had defaults.
- Add an example entry for WWWSUPFILE.

- Given that we tell the compiler that struct ip is packed and 32-bit
aligned, GCC 4.2.1 also generates code for sendudp() that assumes
this alignment. GCC 4.2.1 however doesn't 32-bit align wbuf, causing
the loader to crash due to an unaligned access of wbuf in sendudp()
when netbooting sparc64. Solve this by specifying wbuf as packed and
32-bit aligned, too. As for lastdata and readudp() this currently is
no issue when compiled with GCC 4.2.1, though give lastdata the same
treatment as wbuf for consistency and possibility of being affected
in the future. [1]
- Sprinkle const on a lookup table.

send along the "blksize" option specified in RFC2348,
and the "tsize" option specified in RFC2349.
Add code to parse the TFTP Option Acknowledgement (OACK) packet as
specified in RFC2347.
For TFTP servers which support the "blksize" option, we can
specify a TFTP Data block size larger than the default 512 bytes
specified in RFC1350. This offers greater read performance when
downloading files.
We request an initial size of 1428 bytes, which is less than the
Ethernet MTU of 1500 bytes. If the TFTP server sends back an OACK
packet, then use the block size specified in the OACK packet.
Most times it is usually the same value as what we request.
If the TFTP server supports RFC2348, we will see performance improvements
by transferring files over TFTP with larger block sizes.
If we do not get back an OACK packet, then we most likely we
are interoperating with a legacy TFTP server that does not
support TFTP extension options, so default to the block size of
512 bytes.
(2) If the "tftp.blksize" environment variable is set, then
take that value and use it when sending the TFTP RRQ packet,
instead of 1428. This allows us to set different values of
"tftp.blksize" in the loader, so that we can test out different
TFTP block sizes at run time.

In sendrecv_tftp:
* Upon receving an unexpected block of data or error, resend the ACK
immediately instead of waiting till the expiry of receive data timeout
to resend the ACK.
* change the receive timeout value between retries to be 2xMINTMO.

did not reset the state machine when detecting an
unexpected character.

Add make_dev_physpath_alias(). This interface takes
the parent cdev of the alias, an old alias cdev (if any)
to replace with the newly created alias, and the physical
path string. The alias is visiable as a symlink to the
parent, with the same name as the parent, rooted at
physpath in devfs.
Note: make_dev_physpath_alias() has hard coded knowledge of the
Solaris style prefix convention for physical path data,
"id1,". In the future, I expect the convention to change
to allow "physical path quality" to be reported in the
prefix. For example, a physical path based on NewBus
topology would be of "lower quality" than a physical path
reported by a device enclosure.
