fe0982e586 On start most of sysctl_kern_proc functions use the same pattern: 
locate a process calling pfind() and do some additional checks like
p_candebug(). To reduce this code duplication a new function pget() is
introduced and used.

As the function may be useful not only in kern_proc.c it is in the
kernel name space.

f8b4a766de Additional icache paranoia: non-PLT relocations can modify the text segment. 
It is then important to make sure the icache is synchronized again to
prevent (rare) random seg faults and illegal instructions.

270e7ed83a In contrib/less, cast away const a bunch of times, to make it build

fbf65ae4d9 syscons: provide a first iteration of cngrab/cnungrab implementation 
- put underlying keyboard(s) into the polling mode for the whole
  duration of the grab, instead of the previous behavior of going into
  and out of the polling mode around each polling attempt
- ditto for setting K_XLATE mode and enabling a disabled keyboard

a382ad1946 Correct a logic error in usr.bin/hexdump/conv.c, found by clang. 
Whenever the conv_c() function encounters an incomplete multibyte char,
it peeks ahead.  It also sets p to peekbuf, to indicate it is still
processing the incomplete character.

However, on the next retry, it compares buf against peekbuf, which
always returns false, since both buf and peekbuf are local char arrays,
whose addresses are never the same.

Fix this by comparing against p instead, which was the intention.  Also
turn peekbuf into an array of u_char, to prevent conversion warnings.

53f09b7daf introduce cngets, a method for kernel to read a string from console 
This is intended as a replacement for libkern's gets and mostly borrows
its implementation.  It uses cngrab/cnungrab to delimit kernel's access
to console input.

Note: libkern's gets obviously doesn't share any bits of implementation
iwth libc's gets.  They also have different APIs and the former doesn't
have the overflow problems of the latter.

f6def40e18 kern cons: introduce infrastructure for console grabbing by kernel 
At the moment grab and ungrab methods of all console drivers are no-ops.

Current intended meaning of the calls is that the kernel takes control of
console input.  In the future the semantics may be extended to mean that
the calling thread takes full ownership of the console (e.g. console
output from other threads could be suspended).
