In commit 882e707e40 we changed message
output to go to stdout by default, unless it was an error. The plain()
function doesn't *look* like an error function, but in practice it was
-- it's used to continue multiline messages, and all in-tree uses were
for warning/error.
This is a problem both because we're sending output to the wrong place,
and because in some cases, we were performing error logging from a
function which would otherwise return a value to be captured in a
variable using command substution.
Fix this and straighten out the API by providing two functions: one for
continuing msg output, and one which wraps this by sending output to
stderr, for continuing error output.
Change all callers to use the second function.
When scripting/automating around makepkg, it is sometimes desirable to
know how makepkg will be configured to operate. One example is the
archlinux devtools, which must forward select makepkg.conf variables
into a build chroot (for example PACKAGER) or use those variables itself
(for example {SRC,PKG,LOG}DEST).
The configuration file can be in up to 3 places, and should be capable
of being overridden via environment variables. It is sufficiently
complex to represent distinct functionality, and sufficiently useful to
merit easy accessibility in other scripts, therefore, let us move it
into a publicly exposed utility library.
