This patch fixes full build problems in
https://github.com/llvm/llvm-project/issues/78721 (the header problem).
The `libc.a` target can be built now.
As a separate issue, `check-libc` is failing because undefined symbols
from `libunwind`, which I do not actually know the reason yet. I will be
looking into it.
This patch is large, but is almost entirely just adding casts to calls
to syscall_impl. Much of the work was done programatically, with human
checking when the syntax or types got confusing.

This patch standardizes the error messages when a syscall is not
available to be in the format: "ABC and DEF syscalls are not available."

In this patch we add support for the spawn lib in riscv.
Only small changes were required, the biggest one was to use of dup3
instead of dup2, if the latter is not available. This follows our
implementation of dup2.

The implementation currently ignores all spawn attributes. Support for
them will be added in future changes.
A simple allocator for integration tests has been added so that the
integration test for posix_spawn can use the
posix_spawn_file_actions_add* functions.
