In preparation for using Userspace<T> in Syscall::SC_setkeymap_params
remove the usage of SC_setkeymap_params from when compiling in kernel
mode. In kernel model we would need to do a bunch of explicit FlatPtr
cats to in order to get it to compile, and it's unused anyway, so just
avoid the pain.
- Parsing invalid JSON no longer asserts
Instead of asserting when coming across malformed JSON,
JsonParser::parse now returns an Optional<JsonValue>.
- Disallow trailing commas in JSON objects and arrays
- No longer parse 'undefined', as that is a purely JS thing
- No longer allow non-whitespace after anything consumed by the initial
parse() call. Examples of things that were valid and no longer are:
- undefineddfz
- {"foo": 1}abcd
- [1,2,3]4
- JsonObject.for_each_member now iterates in original insertion order
