8bf9868ec3 Protobuf doesn't directly support heterogeneous lookup with absl::string_view
If the platform does not have `std::string_view` (i.e. `absl::string_view` is not an alias of `std::string_view`) the lookup will cause build failure.

aff27f4559 Update PolicyBuilder to include wrappers for more syscall families that differ between platforms.
New wrappers:

- `AllowEpollWait` (`epoll_wait`, `epoll_pwait`, `epoll_pwait2`)
- `AllowInotifyInit` (`inotify_init`, `inotify_init1`)
- `AllowSelect` (`select`, `pselect6`)
- `AllowDup` (`dup`, `dup2`, `dup3`)
- `AllowPipe` (`pipe`, `pipe2`)
- `AllowChmod` (`chmod`, `fchmod`, `fchmodat`)
- `AllowChown` (`chown`, `lchown`, `fchown`, `fchownat`)
- `AllowReadlink` (`readlink`, `readlinkat`)
- `AllowLink` (`link`, `linkat`)
- `AllowSymlink` (`symlink`, `symlinkat`)
- `AllowMkdir` (`mkdir`, `mkdirat`)
- `AllowUtime` (`utime`, `utimes`, `futimens`, `utimensat`)
- `AllowAlarm` (`alarm`, `setitimer`)
- `AllowGetPGIDs` (`getpgid`, `getpgrp`)
- `AllowPoll` (`poll`, `ppoll`)

Updated wrappers:

- `AllowOpen` now includes `creat`. `openat` already grants the ability to create files, and is the designated replacement for `creat` on newer platforms.
- `AllowStat` now includes `fstatfs` and `fstatfs64`. The comment already claimed that these syscalls were included; I believe they were omitted by accident.
- `AllowUnlink` now includes `rmdir`. `unlinkat` already grants the ability to remove empty directories, and is the designated replacement for `rmdir` on newer platforms.

755f29b35e Correct unwinding stop condition
On successful completion, `unw_step()` returns a positive value
  if the updated cursor refers to a valid stack frame,
  or `0` if the previous stack frame was the last frame in the
  chain. On error, the negative value of one of the error-codes
  below is returned.

92a8247777 Bazel: Add full support for virtual includes
This change adds support for using the `includes`, `include_prefix` and
`strip_include_prefix` attributes of the `cc_library()` rule. Without it,
the libtooling based header generator will not be able to find all
necessary includes as it is much stricter than the current libclang based
one in that regard.

d7fe6cd334 clang_generator: Use fully qualified names
Use locally unqualified types to filter ordered type declarations in
`TypeCollector::GetTypeDeclarations()`. This is necessary, as
`clang::TypeName::getFullyQualifiedName()` and
`TypeDecl::getQualifiedNameAsString()` have different ideas which
qualifiers belong to the name. The former works on `QualType`s, while
the latter deals with the declaration directly. This change decays a
`TypeDecl` into its locally unqualified `QualType`.
