The intention was always that files only get written to *.partial
files and renamed at the end once fully received, but somewhere in the
process that got lost in buffered mode and *.partial files were only
being used in direct receive mode. This fix prevents WaitingFiles
from returning files that are still being transferred.

If DeleteFile fails on Windows due to another process (anti-virus,
probably) having our file open, instead leave a marker file that the
file is logically deleted, and remove it from API calls and clean it
up lazily later.

It used to just store received files URL-escaped on disk, but that was
a half done lazy implementation, and pushed the burden to callers to
validate and write things to disk in an unescaped way.
Instead, do all the validation in the receive handler and only
accept filenames that are UTF-8 and in the intersection of valid
names that all platforms support.

They were scattered/duplicated in misc places before.
It can't be in the client package itself for circular dep reasons.
This new package is basically tailcfg but for localhost
communications, instead of to control.

IPv4 and IPv6 both work remotely, but IPv6 doesn't yet work from the
machine itself due to routing mysteries.
Untested yet on iOS, but previous prototype worked on iOS, so should
work the same.
