…pported (windows, unix, uefi, etc.); modified the Unix implementation to use fchmodat instead of open + fchmod; clarified documentations for set_permissions_nofollow; added a test case for set_permissions_nofollow

Co-authored-by: Daniil Kovalev <dkovalev@accesssoftek.com>

Allow PAC metadata to be passed to `get_fn_addr` and related API changes.

The set of supported attributes is: function * "aarch64-jump-table-hardening" * "ptrauth-auth-traps" * "ptrauth-calls" * "ptrauth-indirect-gotos" * "ptrauth-returns" module * "ptrauth-elf-got" * "ptrauth-sign-personality"

Also add flag for ELF-GOT signing.

Also: * update tests to force dynamic library when targetting pauthtest * various test fixes * introduce end-to-end tests for pauthtest (in run-make)

Currently, rustc can emit a FatalError diagnostic during parsing of literals and tokenstreams. These are handled under the hood as a panic, which means that proc-macro code needed to catch_unwind if it wanted to fallibly parse some code. These still emit diagnostics, so in practice this isn't a full fix, but it at least makes the interface on the macro side a bit more uniform. This is primarily motivated by wasm proc macros which can't use catch_unwind and so this lets the test's output be the same with and without them.

* refactor: move attribute and keywords docs files to core * fix references to `std` * tidy fixes * ignore doc tests w/ explicit_tail_calls * revert `unsafe` example and ignore specifically WASM for `become` doc tests * add explicit note about doube including the docs in `core` and `std` * missed refactoring of doc test ignore * conditionally exclude doc-test containing threading for `wasm-wasip1` * Change exclusion to just `wasi` target_os Co-authored-by: Justin Schilleman <97192655+jschillem@users.noreply.github.com>
