Andrew Dunham a887ca7efe ipn/ipnlocal: improve redactErr to handle more cases 
This handles the case where the inner *os.PathError is wrapped in
another error type, and additionally will redact errors of type
*os.LinkError. Finally, add tests to verify that redaction works.

Brad Fitzpatrick a12aad6b47 all: convert more code to use net/netip directly 
perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.)
    perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. )

    perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. )
    goimports -w .

Then delete some stuff from the net/netaddr shim package which is no
longer neeed.

Brad Fitzpatrick 6a396731eb all: use various net/netip parse funcs directly 
Mechanical change with perl+goimports.

Changed {Must,}Parse{IP,IPPrefix,IPPort} to their netip variants, then
goimports -d .

Finally, removed the net/netaddr wrappers, to prevent future use.

Brad Fitzpatrick cd916b728b ipn/ipnlocal: add start of inter-user Taildrop 
Controlled by server-sent capability policy.

To be initially used for SSH servers to record sessions to other
nodes. Not yet productized into something user-accessible. (Notably,
the list of Taildrop targets from the sender side isn't augmented
yet.) This purely permits expanding the set of expands a node will
accept a drop from.

Brad Fitzpatrick 5e268e6153 ipn/ipnlocal: use delete marker files to work around Windows delete problems 
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.

Brad Fitzpatrick 8570f82c8b ipn/ipnlocal: finish/fix up filename validation & encoding on disk 
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.
