Commit Message

Add HTTP header validation to prevent injection (#2411)

Add ValidateHTTPHeaderName and ValidateHTTPHeaderValue functions to the
validation package to prevent CRLF injection and other header-based
attacks. These functions use golang.org/x/net/http/httpguts for RFC 7230
compliant validation, matching Go's own HTTP/2 implementation.

The validation checks for:
- CRLF injection attempts (\r\n)
- Control characters (null bytes, etc.)
- RFC 7230 token compliance for header names
- Length limits (256 bytes for names, 8KB for values)
