ndb/dns: purge db records on refresh for resolvers, remove old debug and testing code
when ndb/dns runs as a resolver only (cfg.cachedb == 0),
we still want to purge the "local#" db records to reread
dns server configuration or react to changed ip addresses.
removing old poolcheck and dncheck code, these bugs have
been fixed a long time ago.

rio: move the test if w is allowed to change cursor into wsetcursor()
the onscreen cursor shows the cursor of the current
focused window or the window it points at. if there
is no window, then we set the default cursor (nil).

kernel: more (arm) compiler friendly mul64fract()
the arm compiler can lift long->vlong casts on multiplcation
and convert 64x64->64 multiplication into a 32x32->64 one
with optional 64 bit accumulate.
introduce rolor() function to subsitute (a << c) | (a >> (bits(a) - c))
with (a <<< c) where <<< is cyclic rotation and c is constant.
this almost doubles the speed of chacha encryption of 386 and amd64.
the peephole optimizer used to stop when it hit a shift or rol
instruction when attempting to eleminate moves by register
substitution. but we do not have to as long as the shift count
operand is not CX (which cannot be substituted) and CX is not
a subject for substitution.

mk: remove buggy and useless symtab functions (thanks qrstuv)
neither symdel nor symstat were used anywhere. syminit was used but
had no effect. both syminit and symdel dereference pointers after
freeing them. symstat can be tricked into writing beyond the bounds of
its array

rc: fix inband globbing bugs, cleanup
add glob information to the word structure so we wont accidently
deglob quoted strings containing the GLOB. we store Globsize(word)
in in word->glob which avoids recalculating that values and the
check if a word should be globbed quick.
globlist() now substitutes the word inplace avoiding the copying
when all words are literals and avoids recursion.
minor cleanups: use list2str() in execeval(), move octal() to
unix.c, remove the (char*) casts to efree().

upas/marshal: strip trailing whitespace from header values
when using rio auto-complete to resolve file names for the "attach:" and
"include:" headers, the auto-completer might leave whitespaces at
the end of the line which leads upas/marshal to not find the file.

remove š and Š from estonian keymap
Probably the temporary solution to obtain the Estonian uppercase Š and Ž [S and Z with caron (ˇ)] without Shift + AltGr, I note in https://code.9front.org/hg/plan9front/rev/5b6853beadb4 you've written a Shift + AltGr (table 7) for Polish, would be using the caron (ˇ) mapped to key 41 followed by Shift s or Shift z; it was a mistake to earlier map a mode 4 in my fix of /sys/lib/kbmap/ee. It is a bit of an inconvenience to have an AltGr mapping to š and ž, but not a Shift + AltGr mapping to Š and Ž, but that's the best I can do for now. I send a new ee file without the mode 4.

ape: return plan9 error strings from strerror()
when _syserrno() fails to map a plan9 error string to
a unix error number, we copy the plan9 error string
to the per process error buffer "plan9err" and set
errno = EPLAN9.
when strerror() is called with EPLAN9, it returns
a pointer to the plan9err buffer.
