builder: posix_fadvise fixes.
The way we used posix_fadvise was wrong, and yet right!

[PATCH 1/2] utils, builder: Add wrappers for posix_fadvise.
Add wrappers around posix_fadvise and use them in places we were
calling posix_fadvise directly before.
Also in virt-builder we were doing this (and ignoring the result):
posix_fadvise (fd, 0, 0, POSIX_FADV_RANDOM|POSIX_FADV_DONTNEED);
However the POSIX_FADV_* flags are _not_ bitmasks! In fact
POSIX_FADV_RANDOM|POSIX_FADV_DONTNEED == POSIX_FADV_NOREUSE so we were
giving a completely

[PATCH] lib: Use a common function to validate strings.
As discussed in the thread on validating $TERM, it would be good to
have a common function to do this. This is such a function.
The main advantage is it includes unit tests which the previous
functions did not.

By the way, Eric Sandeen solved the problem. It's a genuine
misfeature in ext4 called auto_da_alloc which causes a flush on close
if the file has been truncated (ftruncate or O_TRUNC) and the file
size is zero bytes. I added these patches which work around the
issue:

The first patch is the same (the pure refactoring), but in the second

[PATCH] builder: add index-struct.h as dependency for index-parser-c.c
Just like with index-parse.h, also index-struct.h is a dependency of
index-parser-c.c which automake cannot generate correctly.
Thus, add it manually.

[PATCH nbdkit] file: Implement cache=none and fadvise=normal|random|sequential.
You can use these flags as described in the manual page to optimize
access patterns, and to get better behaviour with the page cache in
some scenarios.
For my testing I used the cachedel and cachestats utilities written by
Julius Plenz (https://github.com/Feh/nocache). I started with a 32 GB
file of random data on a machine with about 32 GB of RAM. At the
beginning of the test I evicted the

[PATCH 0/2] builder: Choose better weights in the planner.
It started out as "this'll be just a simple fix ..."

[PATCH v2 0/2] builder: Choose better weights in the planner.
v1 -> v2:
- Removed the f_type field from StatVFS.statvfs structure.
- New function StatVFS.filesystem_is_remote, written in C.
[Thinking about it, this should probably be called
?is_network_filesystem?, but I can change that before
pushing].
- Use statvfs instead of fstatvfs, and statfs instead of fstatfs.
- Rejigged the comments in builder/builder.ml to make them simpler
