Michael Pratt 569c2b06c4 Statfs Namelen should be NAME_MAX not PATH_MAX
We accidentally set the wrong maximum. I've also added PATH_MAX and
NAME_MAX to the linux abi package.

Brian Geffon 545ea7ab3f Always add AT_BASE even if there is no interpreter.
Linux will ALWAYS add AT_BASE even for a static binary, expect it
will be set to 0 [1].

Zhaozhong Ni be7fcbc558 stateify: support explicit annotation mode; convert refs and stack packages.
We have been unnecessarily creating too many savable types implicitly.

Brian Geffon df5a5d388e Add AT_UID, AT_EUID, AT_GID, AT_EGID to aux vector.
With musl libc when these entries are missing from the aux vector
it's forcing libc.secure (effectively AT_SECURE). This mode prevents
RPATH and LD_LIBRARY_PATH from working.

As the first entry is a mask of all the aux fields set:

Michael Pratt 0dedac637f Trim all whitespace between interpreter and arg
Multiple whitespace characters are allowed. This fixes Ubuntu's
/usr/sbin/invoke-rc.d, which has trailing whitespace after the
interpreter which we were treating as an arg.

Michael Pratt 660f1203ff Fix runsc VDSO mapping
80bdf8a406 accidentally moved vdso into an
inner scope, never assigning the vdso variable passed to the Kernel and
thus skipping VDSO mappings.

Fix this and remove the ability for loadVDSO to skip VDSO mappings,
since tests that do so are gone.

Michael Pratt 062a6f6ec5 Handle NUL-only paths in exec
The path in execve(2), interpreter script, and ELF interpreter may all
be no more than a NUL-byte. Handle each of those cases.
