Currently we only support throwing exception class entries, i.e. stateless exceptions. Ideally we also want to support throwing a ZVal which has a ClassEntry that extends the Exception PHP class. This can be used to throw stateful exceptions which is not uncommon. This PR is missing one piece: `throw_object` will currently `drop` the Zval when the function is completed, causing reference / null pointer errors. It seems `ZVal::Drop` doesn't actually free the zval currently, it just sets the type to NULL (which also breaks things.) Discussed briefly in https://discord.com/channels/115233111977099271/1025314959179120714 on how best to solve this, but I'm not totally clear still! Ideally I think we want `throw_object` to own the `zval` but not free it once the function returns.
This is akin to ExecutorGlobals, but for the process globals
Add support for SapiGlobals
This allows extensions to register and unregister custom stream wrappers
Add helper to get the sapi name
…-support Add support for Zval IS_INDIRECT
…on-object Add support for throwing Exception objects
Add function type helper function
…le-mut Add helper method for function table
Add streams API, ProcessGlobals, FileGlobals and SapiGlobals

Not sure if this is wanted, so this is a first shot into adding a
