Add netutil.FormatRemoteAddr() to avoid repeated net.TCPAddr.String()
allocations on the hot logging path.
- IPv4 addresses use a zero-allocation fast path (custom uint8->ASCII).
- IPv6 falls back to addr.String() with a 1024-entry LRU cache.
- Update logging.LogAccess and variable $remote_addr/$remote_port
getters to use the shared helper.
Eliminates net.JoinHostPort and net.IP.String from top allocators
when access logging is active.
- 所有 *_bench_test.go 文件从 for i := 0; i < b.N; i++ 改为 for b.Loop()
- 部分测试文件从 for i := 0; i < N; ... 改为 for range N 或 for i := range N
- 涵盖模块: cache, handler, http2, http3, loadbalance, logging, lua,
middleware/accesslog, middleware/bodylimit, middleware/rewrite,
middleware/security, netutil, resolver, server, ssl, stream

Conflict: sendfile.go (!linux build tag) was incorrectly modified to
include linuxSendfile and getSocketFd functions which already exist
in sendfile_linux.go.
Resolution: Keep HEAD version (simple fallback returning ENOTSUP) as
Linux implementation is properly separated in sendfile_linux.go.
