Our "Preconditions:" blocks are very useful to determine the input invariants,
but they are bit inconsistent throughout the codebase, which makes them harder
to read (particularly cases with 5+ conditions in a single paragraph).
I've reformatted all of the cases to fit in simple rules:
1. Cases with a single condition are placed on a single line.
2. Cases with multiple conditions are placed in a bulleted list.
This format has been added to the style guide.
I've also mentioned "Postconditions:", though those are much less frequently
used, and all uses already match this style.

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.

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

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

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.

* A segment with filesz == 0, memsz > 0 should be an anonymous only
mapping. We were failing to load such an ELF.
* Anonymous pages are always mapped RW, regardless of the segment
protections.

The number of symbolic links that are allowed to be followed
are for a full path and not just a chain of symbolic links.

We accidentally set the wrong maximum. I've also added PATH_MAX and
NAME_MAX to the linux abi package.

Linux will ALWAYS add AT_BASE even for a static binary, expect it
will be set to 0 [1].

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