Currently we can end up passing EOF to isspace(), which is in fact
libgit's sane_isspace which does:
((sane_ctype[(unsigned char)(x)] & (GIT_SPACE)) != 0)
It is very unlikely that EOF cast to "unsigned char" will end up in a
character that has the GIT_SPACE bit set, but the standard only requires
that EOF be a negative integer, so it could access any value in the
sane_ctype array.
If it does end up returning true for isspace() then this loop will never
terminate, so handle EOF as a special value in the same way as the other
loops in this function.

git-compat-util.h may define various values that affect the
interpretation of system headers. In most places we include cgit.h
first, which pulls in git-compat-util.h, but this file does not depend
on anything else in CGit, so use git-compat-util.h directly.

Use struct strbuf from Git instead of fixed-size buffers to remove the
limit on the length of configuration file lines and refactor
read_config_line() to improve readability.
Note that this also fixes a buffer overflow that existed with the
original fixed-size buffer implementation.

This is a generic function which wanted its own little object file.
