eaff70b558 Use actual ptrace() arguments in example
The semantics of the example remain unchanged. This change is in preparation
for the new Clang based header generator, which will parse most files in C++
mode. `ptrace`'s first argument cannot me implicitly converted from `int` in
C++.

c2631d88ae Improve syscall argument printing for x86-64
Updates syscall arguments mostly according to this list and more recent kernel sources:
https://chromium.googlesource.com/chromiumos/docs/+/master/constants/syscalls.md#x86_64-64_bit

The list includes some more syscalls that were recently added.

Follow-up changes will do the same for x86-32, POWER and AArch64.

accordingly), sandbox logs will be sent back to the sandboxer.

728355da87 Emit non-type template args as part of forward decls
This change allows us to emit forward declarations to classes that are
templated. For headers generated by the proto compiler this is sometimes
necessary.

Note:
- This will only emit types for a single level of template instantiations.
  That is, template template arguments are not supported.
- Typedefs only occurring in template arguments will be fully desugared
  and thus will not be available under their aliased name in the generated
  API code. This is consistent with the Python based generator (which
  does not emit these at all and relies on text extraction).

afa232cc17 Clang generator: Remember "seen" types when collecting related types
This change includes a small refactoring to remember which types the generator
has already seen during header generations. Otherwise we may loop indefinitely
on certain complex types. One such type is `std::FILE` in Clang's libc++.
