Synchronize the i386 and amd64 ddb disassemblers and add support
for many newer instructions.

lint is dead (long live the lint!)
lint is dead (long live the lint!)
Declare play() and pl_main() as __dead, to solve the original problem
remove #if(n)def __LP64__ from the mips64 codebase, as mips32 never really went anywhere.

Welcome to 1989: we can ask for signed chars when we want them
Match bwrite()'s prototype with write()'s, zapping a lint comment
Delete casts to char* of arguments to bwrite() and free()
Kill dead links.
In case imcp_reflect() is called without a given source address
do not try to find a matching address by iterating over a global
list and always use the routing table.

Idea from claudio@, moral support from henning@, ok mikeb@
Remove gratuitous differences between arp and nd6 rtrequests,
no functional change.

Don't bitch about binding into stolen memory on older hardware either.
bugfix update to 1.4.6
For CA generation, go back to using a two-step procedure to create a CSR and
then self-sign it rather than using the "openssl req" shortcut. This allows
us to specify -extfile and thus set the correct certificate extensions so
that stricter SSL implementations will trust this as a CA cert, and matches
how things are done in ssl(8). This is basically a partial revert of r1.77.

lint is gone, and the 'lint' conditional was never in the implementation
namespace, so stop changing behavior when it's #defined

Simpler RM7000 L2 cache initialization code (no longer matches what pmon2000
did, but less awkward). Also make sure that the code changing the K0SEG CCA
value has enough nops, before returning to cached space, to match the
recommended procedure in the RM52xx and RM7000 erratas.
Update to tzcode2014a from ftp.iana.org.
enable qla(4) and qle(4) in GENERIC configs where isp(4) is already
scan for Ed25519 keys by default too
don't count on things that accept arguments by reference to clear
things for us on error; most things do, but it's unsafe form.
correct test that kdf name is not "none" or "bcrypt"
rmail should not reside in /bin.
