update gitignore

Update .gitignore to ignore various files that some of the modules in
modules/ (i.e., the OSv core repository and not osv-apps) seem to build
outside the build/ directory. Also ignore the build.out file (a new file
where scripts/build saves the output of the last "make").

After this patch, "git status" is empty even after building images.

Fixes cloudius-systems#610.

Add line breaks to CODINGSTYLE

Before this commit, viewing CODINGSTYLE.md in a Markdown renderer (such as the GitHub website) would result in some paragraphs (like 5.1 and 5.2) being visually on the same line.

This patch adds trivial newlines between them in the hope of improving readability.

Revert "scripts: Make release images include default configuration"

This reverts commit 1fa7491. We don't
want to automatically pull the CLI, for example, for Redis appliances.
Switch back to requiring release images to explicitly specify their
dependencies.

drivers: do not repeat the pci config parsing

the pci config is already parsed by pci.cc, and thus does not
need to be parsed again in every driver.
The work left to do in the specific drivers is just to make
sense of the BARs.
