b76cb15f26 Rename accessors, move away from time_t API
- `GetPid()` -> `pid()`
- `GetRpcChannel()` -> `rpc_channel()`
- `IsActive()` -> `is_active()`
- Suggest `SetWallTimeLimit(time_t)` -> `SetWallTimeLimit(absl::Duration)`

In addition, remove the protected zero-argument contructor.

eb62bae167 Refactor stack trace handling
- Drop `delim` argument from the `GetStackTrace()` family of functions.
  We only ever used plain spaces.
- Use an `std::vector<std::string>` for the symbolized stack frames and
  adjust the unwind proto accordingly.

This change now prints each stack frame on its own line while skipping
duplicate ones:

1f1de9e229 Fix logging/display of syscall tables
Initializing `absl::Span`s like by assigning them from a temporary
array leaves them pointing to invalid data. Due to the way the linker
initializes these constant tables, _most_ of them will still be valid
_most_ of the time, leading to crashes when running sandboxees with the
`--sandbox2_danger_danger_permit_all_and_log` option.

a51c275a3a Avoid arch names in libffi build directories
This is done by simply building libffi in-tree. Normally, this is not
desirable, but in our case is actually ok, as this is an external
dependency to be pulled in and cleaning the source tree is easy in this
case.

Support LLVM >= 7.0.1 in Clang based header generator

This change glosses over small API changes introduced since LLVM/Clang
7.0.1, which ships with Debian Stable "Buster". Ubuntu 18.04 LTS "Bionic"
also shipped this (and subsequently updated to version 9).

Hence, compiling the generator should now work on all reasonable Debian
based distributions.

726cabe2f7 Fix up generated header include paths
The "hello_sapi" example lives in a different WORKSPACE as it is intended to
show how to embed SAPI in your own projects. However, this is not compatible
with simply running `bazel build //sandboxed_api/...` after checkout.

This change simply replace `copts = ["-I."]` with `includes = ["."]`, so that
generated headers can be found reliably, regardless of how the example is
compiled.
