Revert of Switch SkJpegCode to libjpeg-turbo (patchset #29 id:750001 of https://codereview.chromium.org/1180983002/)

Reason for revert:
DEPS roll failing

Original issue's description:
> Add libjpeg-turbo library (depends on yasm)
> Mangle external function names to avoid conflict with libjpeg
> Take advantage of direct color conversion (RGBA, BGRA, 565)
> Prepare to use jpeg_skip_scanlines (when it is upstreamed)
>

-These platform specific Makefiles are necesary to build yasm on different platforms.  The rest of
-the yasm code is pulled into externals via the DEPS file.
-
-Chromium builds yasm using the below procedure.  We take a few shortcuts.  We mirror Chromium's
-yasm repositories in our DEPS file, and we copy these config files directly from Chromium.
-
-NOTE: We were are currently unable to build yasm for Android on x86 and x86_64.  Instead we are
-using a precompiled binary in the config/android directory.
-TODO (msarett): Fix this!
-
-Excerpt from [chromium] //src/third_party/yasm/README.chromium:
-
-Instructions for recreating the yasm.gyp file.
-  1) Get a clean version of the yasm source tree. The clean tree can be found
-     at:
-
-       src/third_party/yasm/source/yasm
-
-  2) Run configure on the pristine source from a different directory (eg.,
-     /tmp/yasm_build).  Running configure from another directory will keep
-     the source tree clean.
-
-  3) Next, capture all the output from a build of yasm.  We will use the build
-     log as a reference for making the yasm.gyp file.
-
-       make yasm > yasm_build_log 2> yasm_build_err
-
-  4) Check yasm_build_err to see if there are any anomalies beyond yasm's
-     compiler warnings.
-
-  5) Grab the generated Makefile, libyasm-stdint.h, config.h, and put into
-     the correct platform location. For android platform, copy the files
-     generated for linux, but make sure that ENABLE_NLS is not defined to
-     allow mac host compiles to work.  For ios, copy the files from mac.
-
-       src/third_party/yasm/source/config/[platform]
-
-     While we do not directly use the "Makefile" to build, it is needed by
-     the "genmodule" subprogram as input for creating the available modules
-     list.
-
-  6) Make sure all the subprograms are represented in yasm.gyp.
-
-       grep '^gcc' yasm_build_log  |
-       grep -v ' -DHAVE_CONFIG_H '
-
-     The yasm build creates a bunch of subprograms that in-turn generate
-     more .c files in the build. Luckily the commands to generate the
-     subprogram do not have -DHAVE_CONFIG_H as a cflag.
-
-     From this list, make sure all the subprograms that are build have
-     appropriate targets in the yasm.gyp.
-
-     You will notice, when you get to the next step, that there are some
-     .c source files that are compiled both for yasm, and for genperf.
-
-     Those should go into the genperf_libs target so that they can be
-     shared by the genperf and yasm targets.  Find those files by appending
-
-       | grep 'gp-'
-
-     to the command above.
-
-  7) Find all the source files used to build yasm proper.
-
-       grep -E '^gcc' yasm_build_log  |
-       grep ' -DHAVE_CONFIG_H ' |
-       awk '{print $NF }' |
-       sed -e "s/'\.\/'\`//" |  # Removes some garbage from the build line.
-       sort -u |
-       sed -e "s/\(.*\)/'\1',/"  # Add quotes to each line.
-
-     Reversing the -DHAVE_CONFIG_H filter from the command above should
-     list the compile lines for yasm proper.
-
-     This should get you close, but you will need to manually examine this
-     list.  However, some of the built products are still included in the
-     command above.  Generally, if the source file is in the root directory,
-     it's a generated file.
-
-     Inspect the current yasm.gyp for a list of the subprograms and their
-     outputs.
-
-     Update the sources list in the yasm target accordingly.  Read step #9
-     as well if you update the source list to avoid problems.
-
-  8) Update the actions for each of the subprograms.
-
-     Here is the real fun.  For each subprogram created, you will need to
-     update the actions and rules in yasm.gyp that invoke the subprogram to
-     generate the files needed by the rest of the build.
-
-     I don't have any good succinct instructions for this.  Grep the build
-     log for each subprogram invocation (eg., "./genversion"), look at
-     its command inputs and output, then verify our yasm.gyp does something
-     similar.
-
-     The good news is things likely only link or compile if this is done
-     right so you'll know if there is a problem.
-
-     Again, refer to the existing yasm.gyp for a guide to how the generated
-     files are used.
-
-     Here are a few gotchas:
-       1) genmodule, by default, writes module.c into the current
-          directory.  This does not play nicely with gyp.  We patch the
-          source during build to allow specifying a specific output file.
-
-       2) Most of the generated files, even though they are .c files, are
-          #included by other files in the build.  Make sure they end up
-          in a directory that is in the include path for the build.
-          One of <(shared_generated_dir) or <(generated_dir) should work.
-
-       3) Some of the genperf output is #included while others need to be
-          compiled directly.  That is why there are 2 different rules for
-          .gperf files in two targets.
-
-  9) Check for python scripts that are run.
-
-       grep python yasm_build_log
-
-     Yasm uses python scripts to generate the assembly code description
-     files in C++. Make sure to get these put into the gyp file properly as
-     well.  An example is gen_x86_insn.py for x86 assembly.
-
-     Note that at least the gen_x86_insn.py script suffers from the same
-     problem as genmacro in that it outputs to the current directory by
-     default.  The yasm.gyp build patches this file before invoking it to
-     allow specifying an output directory.
-
- 10) Recreate the 'AdditionalOptions!': [ '/analyze' ] block so that VC++
-     /analyze builds won't fail.
-
- 11) If all that's is finished, attempt to build....and cross your fingers.
