- BindSocketThenOpen test was expecting the incorrect error when opening
a socket. Fixed that.
- VirtualFilesystem.BindEndpointAt should not require pop.Path.Begin.Ok()
because the filesystem implementations do not need to walk to the parent
dentry. This check also exists for MknodAt, MkdirAt, RmdirAt, SymlinkAt and
UnlinkAt but those filesystem implementations also need to walk to the parent
denty. So that check is valid. Added some syscall tests to test this.

Added a few tests for write(2) and pwrite(2)
1. Regular Files
For write(2)
- write zero bytes should not move the offset
- write non-zero bytes should increment the offset the exact amount
- write non-zero bytes after a lseek() should move the offset the exact amount after the seek
- write non-zero bytes with O_APPEND should move the offset the exact amount after original EOF
For pwrite(2), offset is not affected when
- pwrite zero bytes
- pwrite non-zero bytes
For EOF, added a test asserting the EOF (indicated by lseek(SEEK_END)) is updated properly after writing non-zero bytes
2. Symlink
Added one pwite64() call for symlink that is written as a counterpart of the existing test using pread64()

These were out-of-band notes that can help provide additional context
and simplify automated imports.

The error set in the loop in createAt was being masked
by other errors declared with ":=". This allowed an
ErrResolveViaReadlink error to escape, which can cause
a sentry panic.
Added test case which repros without the fix.

This fixes the case when an app tries to create a file that already exists, and
is a symlink to itself. A test was added.

If we have a symlink whose target does not exist, creating the symlink (either
via 'creat' or 'open' with O_CREAT flag) should create the target of the
symlink. Previously, gVisor would error with EEXIST in this case

Inode ids are only guaranteed to be stable across save/restore if the file is
held open. This CL fixes a simple stat test to allow it to compare symlink and
target by inode id, as long as the link target is held open.

Also remove comments in InodeOperations that required that implementation of
some Create* operations ensure that the name does not already exist, since
these checks are all centralized in the Dirent.
