The manual page of gmirror describes how gmirror providers can be used
for kernel dumps. Unfortunately, the instruction references
/etc/rc.early, which is no longer a part of rc(8).
Remove references to rc.early and suggest creating an rc(8) service
script instead.
Future work: In the Problem Report on Bugzilla, Lawrence Chen suggested
adding example rc(8) scripts to the gmirror. However, those examples
need to be tested before they become official reference examples in the
base. Also, those scripts should probably land directly to /etc/rc.d,
/usr/share/examples/rc.d, or /usr/share/examples/gmirror instead of the
gmirror manual page.

regcomp: use unsigned char when testing for escapes
- cast GETNEXT to unsigned where it is being promoted to int to prevent
sign-extension (really it would have been better for PEEK*() and
GETNEXT() to return unsigned char; this would have removed a ton of
(uch) casts, but it is too intrusive for now).
- fix an isalpha that should have been iswalpha
It's possible for misuse of cdev KPIs or for bugs in devfs itself to
result in e.g. a cdev object's container being freed while still on the
global list used to populate each devfs mount; see PR 273418 for a
recent example.
Since a node may be marked inactive well before it is reaped from the
list, add a new flag solely to track list membership, and employ it in
some basic list integrity assertions to catch bad actors.
When using printm(), one should always pass a scratch pointer to it.
This is achieved by calling printm with memref
BEGIN { printm(fixed_len, memref(ptr, var_len)); }
which will return a pointer to the DTrace scratch space of size
sizeof(uintptr_t) * 2. However, one can easily call printm() as follows
BEGIN { printm(10, (void *)NULL); }
and panic the kernel as a result. This commit does two things:
(1) adds a new macro DTRACE_INSCRATCHPTR(mstate, ptr, howmany) which
checks if a certain pointer is in the DTrace scratch space;
(2) uses DTRACE_INSCRATCHPTR() to implement a check on printm()'s DIFO
return value in order to avoid the panic and sets CPU_DTRACE_BADADDR
if the address is not in the scratch space.
sockets: re-check socket state after call to pr_rcvd()
