The vdso is enabled, so we can use the sigreturn trampolines
the vdso provides in arch module.

and read from VFS1 and VFS2 files.
- Converted ELF loader to use fsbridge
- Added VFS2 types to FSContext
- Added vfs.MountNamespace to ThreadGroup

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

Initialize the VDSO "os" and "arch" fields explicitly,
or the VDSO load process would failed on arm64 platform.

When execveat is called on an interpreter script, the symlink count for
resolving the script path should be separate from the count for resolving the
the corresponding interpreter. An ELOOP error should not occur if we do not hit
the symlink limit along any individual path, even if the total number of
symlinks encountered exceeds the limit.
Closes #574

Separate the handling of filenames and *fs.File objects in a more explicit way
for the sake of clarity.

When an interpreter script is opened with O_CLOEXEC and the resulting fd is
passed into execveat, an ENOENT error should occur (the script would otherwise
be inaccessible to the interpreter). This matches the actual behavior of
Linux's execveat.

This change simplifies the function signatures of functions related to loading
executables, such as LoadTaskImage, Load, loadBinary.

gVisor does not currently implement the functionality that would result in
AT_SECURE = 1, but Linux includes AT_SECURE = 0 in the normal case, so we
should do the same.

Linux changed this behavior in 16e72e9b30986ee15f17fbb68189ca842c32af58
(v4.11). Previously, extra pages were always mapped RW. Now, those pages will
be executable if the segment specified PF_X. They still must be writeable.

Adds feature to launch from an open host FD instead of a binary_path.
The FD should point to a valid executable and most likely be statically
compiled. If the executable is not statically compiled, the loader will
search along the interpreter paths, which must be able to be resolved in
the Sandbox's file system or start will fail.

This renames FDMap to FDTable and drops the kernel.FD type, which had an entire
package to itself and didn't serve much use (it was freely cast between types,
and served as more of an annoyance than providing any protection.)
Based on BenchmarkFDLookupAndDecRef-12, we can expect 5-10 ns per lookup
operation, and 10-15 ns per concurrent lookup operation of savings.
This also fixes two tangential usage issues with the FDMap. Namely, non-atomic
use of NewFDFrom and associated calls to Remove (that are both racy and fail to
drop the reference on the underlying file.)

All functions which allocate objects containing AtomicRefCounts will soon need
a context.
