Behdad Esfahbod 9caa432d0c [util] Use HB_FALLTHROUGH
Sure, gcc knows to warn about this as well:

../../util/options.cc:175:17: warning: this statement may fall through [-Wimplicit-fallthrough=]
     case 1: m.r = m.t;
             ~~~~^~~~~
../../util/options.cc:176:5: note: here
     case 2: m.b = m.t;
     ^~~~

But HOLY SMOKES, look at clang -Weverything bot message:

options.cc:176:5: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
    case 2: m.b = m.t;
    ^
options.cc:176:5: note: insert 'HB_FALLTHROUGH;' to silence this warning
    case 2: m.b = m.t;
    ^
    HB_FALLTHROUGH;

Right, it's telling me to insert "HB_FALLTHROUGH;" there!!!!!!!!!

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert()
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

Revert file blob sanitization and index checking (#1062)
As https://github.com/harfbuzz/harfbuzz/pull/1059#issuecomment-397912812 we
like to still work with blobs that harfbuzz itself can't handle directly that are failing sanitization
currently apparently.

Ebrahim Byagowi c53697d3f2
Verbose fail when something is wrong with hb-shape/hb-view input font file (#1059)
This checks if the blob isn't empty and uses `hb_face_count`
to see if the font file passes the simple font file sanitization
so can detect if the input is actually a font and checks also
whether input font-index is out of range.

Ebrahim Byagowi aa0c5df419
Fix reading fonts from stdin (#1060)
We were passing the font path directly to freetype so rendering
was broken when we are getting the font from stdin.

This fixes it by using FT_New_Memory_Face instead.

This fixes:
* build/util/hb-view /dev/stdin text < font.ttf
* build/util/hb-view - text < font.ttf
* cat font.ttf | build/util/hb-view - text

but doesn't work on
* cat font.ttf | build/util/hb-view /dev/stdin text

which I will try to fix separately.

Behdad Esfahbod e60350551a [hb-shape] Improve shaping-debug output
Before, that was printed using --debug (and in both hb-shape and hb-view).
Changed it, now hb-shape has a new command-line argument called --show-messages.
When invoked, it also respects other output formatting options.  The messages
are better formatted and printed to te same place that hb-shape output is
directed to.  Previously they were written to stderr.

Chun-wei Fan 998e8dda93 util: Fix build on Visual Studio
Use the fallback implementation for lround() only on pre-2013 Visual
Studio, and ensure we are clear about the types of the parameters for
lround() and scalbnf(), since Visual Studio can be quite picky on
ambiguous parameter types.  Also, use g_ascii_strcasecmp() rather than
strcasecmp() as we are already using GLib for this code and we are
assured that g_ascii_strcasemp() is available.

For scalbnf() on pre-2013 Visaul Studio, a fallback implementation is
needed, but use another forced-included header for those compilers, which
will be added later.

Also use (char)27 on Visual Studio builds as '\e' is not a recognized
escape sequence, which will do the same thing.

Behdad Esfahbod 642135f3b2 [util] In --debug mode, duplicate font data
This has the effect that the font data will end up in a memory
section malloc()ed exactly to its size.  This gives us better
valgrind detection of out-of-bounds access.

Previously, the font data was placed in a mmap()ed section or
GString-allocated area, which didn't have proper protections
at the end when running under valgrind.
