Revert of Pdfium: Fix fonts leaking on ClosePage. (patchset #10 id:180001 of https://codereview.chromium.org/2158023002/ )
Reason for revert: Causes heap-use-after-free. See crbug.com/647612. Original issue's description: > Fix memory leaking on ClosePage. > CFX_FontCache refactoring: > after this CL: Only one global CFX_FontCache used. Any cached items from it, are released, when its are not used. > > BUG=79367,48791 > > The fonts was not cleared after unloading pages. > > Test pdf: > > http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf > > For this file, we have ~5 fonts per page, which equal ~1 Mb per page. > In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory. > > memory usage of PDF Plugin: > before this CL: ~660 Mb > after this CL: ~100 Mb > > Committed: https://pdfium.googlesource.com/pdfium/+/cde5101eb15b24519e89fa500fe37038bc8e2201 TBR=tsepez@chromium.org,brucedawson@chromium.org,npm@chromium.org,art-snake@yandex-team.ru # Not skipping CQ checks because original CL landed more than 1 days ago.
