Remove an `inttypes.h` header that is too large in scope, and far too
public.

For Visual Studio 2012 and earlier (ie, `_MSC_VER < 1800`), we do need
to include `stdint.h` in our public headers, for types like `uint32_t`.

Internally, we also need to define `PRId64` as a printf formatting
string when it is not available.

ci: publish documentation on merge

When a commit is pushed or merged into one of the release branches
(master, maint/*) then push the documentation update to gh-pages.

This reverts commit 2a4e866a43e3db1e2be8e2a3d986ddc9f855d2bc.

When a continuous integration build runs (ie a commit is pushed or
merged into one of the CI branches, `master` or `maint/*`) then push the
rebuilt documentation into the `gh-pages` branch.
