5339c75ee6 [sfnt] Better checks for invalid cmaps (2/2) (#46019).
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed
cmaps that use 32bit values.  This commit tries to improve that.

392cf22f8a Another adjustment to header locations.
This change is a result of a discussion thread on freetype-devel

  http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html

Re-introduce the `freetype2' subdirectory for all FreeType header
files after installation, and rename the `freetype2' subdirectory in
the git repository to `freetype'.

* include/freetype2: Renamed to...
* include/freetype: This.

* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS): Updated.
Update creation of `ftconfig.h'.
Install generated `ftconfig.h'.

* Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.

* builds/amiga/include/config/ftconfig.h, builds/freetype.mk
(PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work),
builds/unix/freetype2.in: Updated.

* builds/unix/freetype-config.in: Updated.
* builds/unix/configure.raw: Don't check for `rmdir'.
* builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable
according to the autoconf info manual.
* builds/unix/install.mk (install, uninstall,
distclean_project_unix): Update and simplify.

* builds/wince/*, builds/windows/*: Updated.

* devel/ft2build.h, include/ft2build.h: Updated.

* include/freetype2/config/ftheader.h,
include/freetype2/internal/ftserv.h,
include/freetype2/internal/internal.h: Update all header file
macros.

* src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated.

fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

* include/freetype/tttables.h (TT_OS2): Add fields

this structure only as a pointer through `FT_Get_Sfnt_Table', there
shouldn't be any ABI problems.

41632b58ef [arm] Fix thumb2 inline assembly under LLVM.
When using `ADD' with an immediate operand, the instruction is
actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
immediate operand cannot exceed 4095.  It will fail to compile with
LLVM.

However, in GCC, due to some legacy compatibility considerations,
`ADD.W' will be automatically emitted when the immediate operand is
larger than 4095.
