Fixes CVE-2012-2792

Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind

Do not build from scratch the section header for each section, but build
it using the previous level buffer, thus improving efficiency.

Also fix some few corner cases related to numbering which are exposed by
the pending disposition patch.

Regular section fields nested in a regular section are now prefixed by
the nested section name.

This is required by the pending change related to disposition.

This practice is not supported by the MinGW developers, and even requires
patching the MinGW runtimes in newer versions. Furthermore, we now support
build with MSVC, so this section is rendered useless.
