Make `blog_load` return a ptr_vector which is
consumed by the code that uses blog entries.
Greatly clean up WWW page generation by using
stralloc and strftime and the ptr_vector
infrastructure.
Needs to be tested. :-)

More cleaning up construction of arrays of things.
Introduce a utility function called, `split_on_space`
that tokenizes a string on a space character; use
it in most places where `strtok()` had been called.
More use of the ptr_vector type. Introduce a utility
function to get access to the pointers without consuming
the vector; this is used in the files code.

A repeated pattern in Magicka is to append to dynamically
sized arrays via malloc()/realloc(). Introduce the notion
of a "pointer vector": that is, a growable vector of
pointers, that can be reused to implement that logic more
safely and efficiently (this implementation uses power-of-two
growing).
Many malloc()/realloc() calls were not checked; these
assert() that the return value from realloc() is not NULL.
Add a method to consume the pointer vector: that is, realloc()
it to the current length and return the underlying pointers.
Make the `fmt` argument to dolog() const.
Include <sys/wait.h> in bluewave.c to squash a warning.
