exit(3) is implemented by the runtime and performs a number of shutdown
actions before ultimately calling _exit(2) to terminate the program. We
historically named the syscall table entry `exit` rather than `_exit`,
but this requires special handling in libc/libsys to cause the `_exit`
symbol to exist while implementing `exit` in libc.
Declare the syscall as `_exit` and flow that through the system.
Because syscall(SYS_exit, code) is fairly widely used, allow a
configured extra line in syscall.h to define SYS_exit to SYS__exit.
I've found no external uses of __sys_exit() so I've not bothered to
create a compatability version of this private symbol.

We haven't used this since commit be67ea40c5a0 in 2021 so stop carrying
it forward.
Also remove support for setting the list in syscalls.conf via the
capenabled variable. This was last used by cloudabi (removed in 2021
by commit cf0ee8738e31).

* Modules can be called as standalone scripts to generate a specific
file
* Data and procedures are performed by objects instead of procedual code
* Bitmasks are replaced by declarative types
* Temporary files are no longer produced, writing is stored in memory
* Comments provide explanation to functions and semantics
