Fixes

• Generic functions and values incorrectly would not require a prefix. #3374
• Arena allocator would error in safe mode when freeing the last memory and the arena was full. #3378
• LinkedList push_front_all was appending in the wrong order.
• BitSet.len would yield the size of the underlying type, not the length.
• RFC3339 formatting would yield incorrect value for microseconds.
• --obj will always retain the object files. #3380
• ThreadGroup with function returning void was broken.
• Timed tcp::connect always failed with io::GENERAL_ERROR instead of the real result.
• Compile time struct with zeroed union member access causes compiler error #3382.
• Generic methods checked before the generic type is fully registered.
• Math function _erff invoked C erf function instead of erff function #3391
• Defining local constants inside a macro causes it to fail to @const fold. #3397
• AES CTR would lose sync on data not multiples of 16.
• In some cases, on macros rethrowing optional values codegen could fail.
• Json accepted incorrectly accepted \v as whitespace.
• JSONC parsing on unterminated comments would loop indefinitely.
• ZII array constdef would cause an assert. #3411
• Calling a constant void macro inside a macro stops it from being constant. #3410
• Using io::struct_to_format with $force_dump = true failed to compile.
• $foo += 1 would not do a copy, leading to incorrect update of $foo. #3400
• foreach (foo::Type t : x) would not parse properly. #3423
• Docgen improvements and fixes: emit attrdef declarations/docs, include alias doc comments, render @return contracts, exclude compiler_rt when --emit-stdlib=no, and omit empty JSON fields for slimmer output #3422.
• Several uses of InStream didn't properly handle io::EOF.
• Fixes to memory handling during zip loading.
• Multireader reading after a final empty read would crash.
• RISC-V structs with mixed FP and integer fields were corrupted when passed or returned by value. #3428
• io::read_all didn't handle split data.
• Scanner would not correctly handle chunked data.
• Gzip reader couldn't handle a stream without seek.
• io::printf("%3d", 1) would return the wrong printed length. #3432
