Dirents are ref-counted, but Pipes are not. Holding a Dirent inside of a Pipe
raises difficult questions about the lifecycle of the Pipe and Dirent.
Fortunately, we can side-step those questions by removing the Dirent field from
Pipe entirely. We only need the Dirent when constructing fs.Files (which are
ref-counted), and in GetFile (when a Dirent is passed to us anyways).

sendfile can be called for a big range and it can require significant
amount of time to process it, so we need to handle task interrupts in
this system call.

Pipe internals are made more efficient by avoiding garbage collection.
A pool is now used that can be shared by all pipes, and buffers are
chained via an intrusive list. The documentation for pipe structures
and methods is also simplified and clarified.
The pipe tests are now parameterized, so that they are run on all
different variants (named pipes, small buffers, default buffers).
The pipe buffer sizes are exposed by fcntl, which is now supported
by this change. A size change test has been added to the suite.
These new tests uncovered a bug regarding the semantics of open
named pipes with O_NONBLOCK, which is also fixed by this CL. This
fix also addresses the lack of the O_LARGEFILE flag for named pipes.

This does not actually implement an efficient splice or sendfile. Rather, it
adds a generic plumbing to the file internals so that this can be added. All
file implementations use the stub fileutil.NoSplice implementation, which
causes sendfile and splice to fall back to an internal copy.
A basic splice system call interface is added, along with a test.

ilist:generic_list works faster (cl/240185278) and
the code looks cleaner without type casting.

More helper structs have been added to the fsutil package to make it easier to
implement fs.InodeOperations and fs.FileOperations.

Added events for *ctl syscalls that may have multiple different commands.
For runsc, each syscall event is only logged once. For *ctl syscalls, use
the cmd as identifier, not only the syscall number.

We have been unnecessarily creating too many savable types implicitly.
