- logging: pre-allocate fresh slice for request field to avoid mutating
fasthttp internal buffers via append into slices with excess capacity
- mimeutil: move defaultMIME fallback before cache insertion so unknown
extensions are consistently cached as application/octet-stream
- builtin: use -0700 timezone format instead of hardcoded +0800; cache
generated request_id in UserValue to prevent different IDs per expansion
- variable: initialize maps in fallback Context to prevent nil map panic
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.
