Luke Shumaker f7efa6a93d makepkg: Better error messages for versions in (check, make, opt)depends/provides/conflicts
Given the depends

    depends=('foo>=1.2-1.par2')

and the error message

    ==> ERROR: pkgver in depends is not allowed to contain colons, forward slashes, hyphens or whitespace.

One would be lead to believe that the problem is that they gave a pkgrel in
depends at all, not that the pkgrel contains letters.

Each of the (check,make,opt)depends, conflicts, and provides linters use a
glob to trim off properly formed epoch an rel from the full version string,
and pass the remainder to check_pkgver().  This does a good job of
accepting/rejecting full versions, but doesn't do a good job of generating
good error messages when rejecting if it's because of the epoch or rel.

1. Factor out check_epoch() and check_pkgrel() from lint_epoch() and
   lint_pkgrel(), similarly to check_pkgver().
2. Add a check_fullpkgver() that takes a full [epoch:]ver[-rel] string and
   splits it in to epoch/ver/rel, and calls the appropriate check_ function
   on each.
3. Use check_fullpkgver() in the {,check,make,opt}depends, conflicts, and
   provides linters.
