Create top-level public/ header directory.

These are the only files that embedders of PDFium should be including.
They are entirely self-contained, and compile cleanly against -Wall so
as to not offend the code that may include them.

Having done this, we can see that chromium is pulling in two additional
files from the fpdfsdk/include/pdfwindow directory, which is not guaranteed
to work.

A few files are renamed, adding an "_" to make the names consistent.
The exception is fpdfview, which is doc'd as such in the doc.

Naturally, paths will need updating in a handful of files in chrome
when this rolls in.

-// Return value:
-//			The destination handle of a named destination, or NULL if no named destination corresponding to |index|.
-// Comments:
-//			Call this function twice to get the name of the named destination:
-//			1) First time pass in |buffer| as NULL and get buflen.
-//			2) Second time pass in allocated |buffer| and buflen to retrieve |buffer|, which should be used as wchar_t*.
-//			   If buflen is not sufficiently large, it will be set to -1 upon return.
