apocelipes a92c80eb40 net,net/netip: implement the encoding.(Binary|Text)Appender
Implement the encoding.TextAppender interface for "net.IP".

Implement the encoding.(Binary|Text)Appender interfaces for
"netip.Addr", "netip.AddrPort" and "netip.Prefix".

"net.IP.MarshalText" also gets some performance improvements:

All exported types in the standard library that implement the
"encoding.(Binary|Text)Marshaler" now also implement the
"encoding.(Binary|Text)Appender".

Zeke Lu c53390b078 net: store IPv4 returned from cgo resolver as 4-byte slice net.IP
net.IP states that a 16-byte slice can still be an IPv4 address.
But after netip.Addr is introduced, it requires extra care to keep
it as an IPv4 address when converting it to a netip.Addr using
netip.AddrFromSlice.

To address this issue, let's change the cgo resolver to return
4-byte net.IP for IPv4. The change will save us 12 bytes too.

Please note that the go resolver already return IPv4 as 4-byte
slice.

The test TestResolverLookupIP has been modified to cover this
behavior. So no new test is added.

Fixes #53554.

Chris Stockton aff3aaa47f net: halve the allocs in ParseCIDR by sharing slice backing
Share a slice backing between the host address, network ip and mask.
Add tests to verify that each slice header has len==cap to prevent
introducing new behavior into Go programs. This has a small tradeoff
of allocating a larger slice backing when the address is invalid.
Earlier error detection of invalid prefix length helps balance this
cost and a new benchmark for ParseCIDR helps measure it.

This yields a ~22% speedup for all nil err cidr tests:

  name               old time/op    new time/op    delta
  ParseCIDR/IPv4-24    9.17µs ± 6%    7.20µs ± 7%  -21.47%  (p=0.000 n=20+20)

  ParseCIDR/IPv6-24      68.0 ± 0%      34.0 ± 0%  -50.00%  (p=0.000 n=20+20)

Including non-nil err cidr tests gains around 25%~:

Russ Cox 7f9255c212 net: revise IP.String result for malformed IP address to add ? back
In earlier versions of Go the result was simply "?".
A change in this cycle made the result echo back the hex bytes
of the address, which is certainly useful, but now the result is
not clearly indicating an error. Put the "?" back, at the beginning
of the hex string, to make the invalidity of the string clearer.

Mikio Hara 055ecb7be5 net: fix inconsistent errors
These a series of changes fix inconsistent errors on the package net
APIs. Now almost all the APIs return OpError as a common error type
except Lookup, Resolve and Parse APIs. The Lookup, Resolve and Parse
APIs return more specific errors such as DNSError, AddrError or
ParseError.

An OpError may contain nested error information. For example, Dial may
return an OpError containing a DNSError, AddrError, unexposed type/value
or other package's type/value like the following:
	OpError{/* dial info */, Err: &DNSError{}}
	OpError{/* dial info */, Err: &AddrError{}}
	OpError{/* dial info */, Err: <unexposed type or value>}
	OpError{/* dial info */, Err: <other package's type or value>}

and Read and Write may return an OpError containing other OpError when
an application uses io.Copy or similar:
	OpError{/* for io.Reader */, Err: &OpError{/* for io.Writer */}}

When an endpoint is created for connection-oriented byte-stream
protocols, Read may return an io.EOF when the connection is closed by
remote endpoint.

Fixes #4856.
