Use soft dirty bits on Linux (initial implementation, off by default)

Issue #265 (bdwgc).

* doc/README.macros (GC_PREFER_MPROTECT_VDB): Mention SOFT_VDB.
* doc/porting.md (Adding Platforms to gcconfig.h): Likewise.
* include/private/gcconfig.h: Likewise.
* doc/gcdescr.md (Generational Collection and Dirty Bits): Document
SOFT_VDB.
* os_dep.c: Likewise.
* include/private/gcconfig.h [MPROTECT_VDB && GC_PREFER_MPROTECT_VDB
|| DEFAULT_VDB || GC_DISABLE_INCREMENTAL] (SOFT_VDB): Undefine.
* include/private/gcconfig.h [SOFT_VDB] (MPROTECT_VDB): Likewise.
* include/private/gcconfig.h [USE_PROC_FOR_LIBRARIES
&& GC_LINUX_THREADS]: Refine comment.
* include/private/gcconfig.h [!PCR_VDB && !PROC_VDB && !MPROTECT_VDB

Do not define if SOFT_VDB.
* include/private/gc_priv.h [CHECKSUMS && SOFT_VDB]
(GC_arrays._written_pages): Declare field.
* os_dep.c [SOFT_VDB && !PROC_READ] (PROC_READ): Define.
* os_dep.c [!MSWIN32 && !MSWINCE && !CYGWIN32 && SOFT_VDB]
(GC_setpagesize): Set GC_page_size to GETPAGESIZE().
* os_dep.c [SOFT_VDB] (VDB_BUF_SZ, PAGEMAP_ENTRY_SZ, PM_SOFTDIRTY_OFS,
PM_SOFTDIRTY_MASK): Define macro.
* os_dep.c [SOFT_VDB] (soft_vdb_buf, clear_refs_fd, pagemap_fd):
Declare static variable.
* os_dep.c [SOFT_VDB] (open_proc_fd): New static function.
* os_dep.c [SOFT_VDB] (GC_dirty_init): Implement.
* os_dep.c [SOFT_VDB] (GC_soft_read_dirty): New inline function.
* os_dep.c [!GC_DISABLE_INCREMENTAL && SOFT_VDB] (GC_read_dirty): Call
GC_soft_read_dirty().
* os_dep.c [CHECKSUMS && SOFT_VDB] (GC_or_pages): Define function.
* os_dep.c [!GC_DISABLE_INCREMENTAL && CHECKSUMS && SOFT_VDB]
(GC_page_was_ever_dirty): Process GC_written_pages.
* tests/test.c [!PCR && !GC_WIN32_THREADS && !GC_DISABLE_INCREMENTAL
&& (TEST_DEFAULT_VDB || !DEFAULT_VDB) && SOFT_VDB] (main): Print that
dirty bits information is obtained from /proc if incremental mode.
