Specifically, change the www_last10 HTML rendering logic
to use stralloc and strftime(). This eliminates a lot of
duplication.
It would be easier to test this with a unit test if the
logic of reading the last10 entries from a file were
separated from the HTML rendering logic. An area for
future enhancement.
Also start in on www_email.c, which is the last bastion
of significant realloc() use for page generation. An
explicit goal is to get rid of unsafe string handling
functions such as strcpy, strcat, sprintf, etc.
