Go back ot using 0x%x instead of %#x because we don't always support the
format. See subr_prf.c

fix warnings, printf formats, etc.

Obtain and/or use ETHER_ADDR_LEN.

Separate the IP and UDP code paths inside libsa, so I can add HTTP booting
later.

branches: 1.30.6; 1.30.8;
Remove __P().

Replace time_t values in libsa sources with the following two types
to avoid unnecessary 64 bit ops which would make binaries larger:

satime_t (currently unsigned int):
numbers in seconds returned by the machine dependent getsecs() function
which are used to measure relative time

saseconds_t (currently int):
numbers in seconds used to specify timeout to network drivers

Per discussion on current-users.

Fix a warning in #ifdef RARP_DEBUG. PR kern/20314

- use mem* instead of b* routines, and kill the b* routines.
- use the mem* routines from libc.
XXX: There will be some lossage, but I am fixing it.

fix pointer size in debug message

Update for the improvements to libsa, and don't reference libkern.h.

Don't use private copy of old netinet/if_ether.h.
Use <net/if_ether.h> for ethernet specific definitions, and insert private
definitions for ARP if needed. (The new ARP macros in <net/if_arp.h> are
not used because they create larger code, and we really don't need more
than ethernet/ip support here.)

Avoid user space headers for standalone programs.
Don't use sys/lib/libkern or sys/lib/libz if not standalone
(ie, user space test programs).

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

backout previous kprintf changes

printf -> kprintf, sprintf -> ksprintf

missing semicolon

More cleanup: change some private types to eliminate casts,
replace some "goto xxx" with return(-1). (mostly cosmetic)

Another round of clean up, including fixes presented by Matthias Drochner
(PR#1404). Things to be noted:
- all IP addresses are now `struct in_addr's.
- the function rarp_getipaddress() no longer return `myip'; in stead
it returns -1 on failure (errno set), 0 on success. `myip' is set
as a size-effect.

Clear up some size_t/ssize_t confusion.

Changes from Gordon Ross:
a) check against `my' ethernet or broadcast addresses done in
ether.c
b) changed interface to readether() to provide ethertype info
c) respond to arp requests when appropriate.
First two are clean-up. Last fixes hp300 and presumably mvme68k netboot
code.

Fix ARP opcode, add more debugging prints.

Various:
* Fix some misused types.
* Encapsulate the protocols better.
* Rearrange the RPC stuff to work more like the kernel. (Needs more work.)
* Remove a bunch of extra hair when reading a file over NFS.
* Use RPCAUTH_UNIX when talking to the NFS server.
