refactor the ld(4) DIOCCACHESYNC hook into general ioctl hook, so that attachments
would be able to implement arbitrary other ioctls

Modularize the ld driver and all of its attachments. Ensure that all
parents are capable of rescan (or otherwise provide a means of attaching
children post-initialization).

modify ldattach() to have default strategy as a parameter

branches: 1.17.2;
Convert sys/dev to use <sys/rndsource.h>.

branches: 1.16.6;
- remove unused variables
- move debugging code inside debugging sections

branches: 1.15.6; 1.15.10;
Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

branches: 1.14.8; 1.14.12;
Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.

branches: 1.13.16;
Complete device_t/softc split for the ld(4) attachments. This should
prevent crashes while attaching a drive.

Patch supplied by Juan RP in PR kern/39468.

Add a flags argument to the ld(4) flush handlers, and call these with a
"poll" flag when called from ld_shutdown().

This is the infrastructure part of kern/38655 - in itself it doesn't
fix the panic referenced in that PR.

XXX: At least ld_twa.c and perhaps ld_iop.c and ld_icp.c need to
check for this new poll flag and do something useful.

branches: 1.11.2; 1.11.4; 1.11.6;
First part of twa(4) improvements:
- more/better diagnostic messages
- dynamically allocate units in preparation for 9650+ support
- better distribute queue slots over disks according to size
- drain large request queue on 9550
- keep track of resets, will be needed for 9650.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

Don't depend on uvm_extern.h pulling in proc.h.
