Implement turns

[paulomorgado]

NEW FEATURES:

• turns implementation

PERFORMANCE OPTIMIZATIONS:

Memory Management:

• Add PooledSegmentedBuffer<T> for efficient buffer pooling with ArrayPool<T> integration
• Implement MemoryOperations helper for optimized memory operations
• Add ValueStringBuilder for stack-allocated string building to reduce heap allocations
• Introduce SearchValues for optimized span-based searching
• Use NetEscapades.EnumGenerators to optimize enum usage.

Socket and Network Layer:

• Refactor NetServices with connection pooling and reduced allocations
• Add SocketConnection abstraction with concrete implementations (SocketTcpConnection,
  SocketUdpConnection, SocketTlsConnection) for better resource management
• Optimize IPSocket with span-based parsing and reduced string allocations
• Enhance PortRange with improved allocation patterns

System Utilities:

• Add BinaryOperations for bit manipulation optimizations
• Implement EncodingExtensions for efficient encoding/decoding operations
• Add HashExtensions for streamlined hash computations

Crypto and Security:

• Refactor Crypto class with reduced allocations
• Add SslClientAuthenticationOptions and SslStreamExtensions for down-level targets
• Optimize CRC32 implementation

Data Serialization:

• Add SipSorceryJsonSerializerContext for AOT-friendly JSON serialization
• Remove legacy JSONWriter and JsonParser in favor of System.Text.Json

Protocol Implementations:

• Optimize RTP/RTCP packet handling with span-based operations
• Refactor SCTP chunks for reduced allocations
• Improve SDP parsing with ValueStringBuilder
• Optimize STUN attribute handling

Codec Optimizations:

• Extensive refactoring of codes to optimize memory usage
• Update AudioEncoder with more efficient buffer handling

HIGH-PERFORMANCE LOGGING:

Structured Logging Infrastructure:

• Introduce LoggerMessageAttribute source generator pattern across all modules
• Add domain-specific logging extensions for compile-time log message generation

Benefits:

• Zero-cost logging when log level is disabled
• Compile-time string formatting
• Reduced memory allocations in hot paths
• Type-safe structured logging
• Improved debuggability with consistent log patterns

MODERNIZATION:

• Standardize on .NET 10.0 and C# 14.0
  • Used Meziantou.Polyfill for down-level targets
    • Added other polyfills to keep the source code clean of conditional compilation symbols.
  • Introduce BouncyCastleExtensions for down-level targets

RETARGETING:

• Removed .NET Framework targets from libraries
• Keep dependencies on the lowest supported LTS version for non-.NET targets
• Target the same channel for supported .NET targets

SUPPORTING CHANGES:

Type System:

• Refactor TypeExtensions
• Add IByteSerializable interface for consistent serialization
• Add ProtocolTypeExtensions for protocol type handling

Testing:

• Update existing tests to use new optimized APIs
• Replaced Serilog with MartinCostello.Logging.XUnit

Supersedes #1335, #1338, #1407, #1414, #1423
