code assumed the accessdir() call would always mark the block dirty, but
this is not the case when noatime flag is enabled. this was reported by
michael in bug:

introduce wificfg() function to convert ether->opt[] strings
to wifictl messages, which needs quoting for the value. so
etherX=type=iwl essid='something with spaces' works.
from charles forsuth:
because the previous version thought OINDEX might have a side effect, it
stopped it building a tower of them.
probably the best thing is to limit that anyway, since each one consumes
2-3 registers, so towering them can
keep even more active, and the x86 hasn't got that many.
the quick hack is to return that case to the earlier state by treating
OINDEX as a side-effect in side().
it's not a bad thing to do in the OSTRUCT case, for similar reasons: it's
better to collapse the indexed pointer
into a direct register, instead of repeating the indexing operation through
the copying of the value.
OINDEX isn't a machine-independent operation, so it doesn't affect the uses
in ../cc
- cover more cases that have no side effects
- ensure function has complex FNX
- pull operators out of OFUNC level
- rewrite OSTRUCT lhs to avoid all side-effects, use regalloc() instead of regret()
maximum file size is 4GB-1 as the file length is stored in
a 32 bit long. make sure it doesnt overflow on write or
or truncate. interpret the file length as unsigned. pass
vlong to readfile()/writefile()/truncfile() so we can
handle overflows and not just ignore the upper bits.
- fix missing runlock(ifc) when ifcid != a->ifcid in rxmitsols() (thanks erik quanstro)
- don't leak packets when transfering blocks from arp entry hold list to droplist
- free rest of droplist when bwrite() errors in arpenter(), remove useless checks (ifc != nil)
- free arp entry hold list from cleanarpent()
- consistent use of nil for pointers
sprint() will replace invalid utf8 sequences with U+FFFD
which caused directory reads and stats to return the wrong
filename. just strcpy the name bytes.
