Envsetup.sh (lunch) relies on config.mk to get build varaible values; while
config.mk may rely on envsetup.sh to set up JAVA_HOME/PATH.
Without this change config.mk may be checking the host JDK tools before
JAVA_HOME/PATH get set up.

When searching device, product, or hardware, allow
find to follow symlinks.

Add KATI_EMULATE_FIND=false to allow disabling the find
emulator which changes findleaves.py behavior wrt
symlinks.

BUG=24605247
TEST=works with CL:783781 (without the find wrapper in that CL)

Specifically, do not error out if no installable apps are found.

- When creating an archive of all the apps, and if no apps exist
for the target, generate an empty archive file.
- If building for a target with no installable jar(s) or apk(s),
generate an empty package stats file.

The former is just an output artifact. The latter is used
by the upload_pkg_stats.py script which correctly handles
an empty input file.

zipalign depends on libandroidfw, and some setups don't include frameworks/base.

Pass -X to zip so that Unix UID/GID and extra timestamps aren't
saved into the zip files.

Add a new option to zipalign, -t, to replace all timestamps with static
timestamps (2008 Jan 1 00:00:00). Use this for all non-APK zip files.
APK zip timestamps are set based on the certificate date in SignApk.

- For unmodified "make product-graph" and "make dump-products",
  load only the current product configuration makefiles. This is much
  faster than loading all product makefiles.
- For "make product-graph ANDROID_PRODUCT_GRAPH=--all",
  "make dump-products ANDROID_DUMP_PRODUCTS=all", load all product
  makefiles.
- Move product-graph.mk out of build tasks, so we can skip loading all
  the Android.mks, which takes long and we don't really need them.
  More importantly, with all product makefiles loaded, modules in
  Android.mks are prone to clash (if they are conditionally included
  by variables set up in product makefiles) and lead to parse-time
  error.

Some vendor product makefiles call $(inherit-product) on the same
product makefile with different paths, by using "../" in relative paths.
However inherit-product requires unique path as ID for a product
makefile, for bookkeeping purpose.
Normalize the product makefile path in inherit-product, if the path
contains "../".

make 3.81 has a bug where combining an up-to-date .INTERMEDIATE rule
with -j causes an infinite loop (http://savannah.gnu.org/bugs/?15919).
.INTERMEDIATE was only necessary to support multiple outputs while only
running a command once, remove .INTERMEDIATE by replacing
$(KATI_OUTPUTS) dependencies with $(KATI_BUILD_NINJA).  We can assume
that $(KATI_NINJA_SH) will be updated at the same time as
$(KATI_BUILD_NINJA), and not explicitly depend on it.

Also remove generateonly and fastincremental, which are no longer
necessary and were overcomplicating ninja.mk.  kati now always runs due
to FORCE, and ninja is run by a phony rule that depends on
$(KATI_BUILD_NINJA).

Don't generate recovery.img when calling 'make dist' if
TARGET_NO_RECOVERY is set. The build system passes the flag to the
packaging script which then generates recovery.img conditionally.

kati takes the first @echo command in a rule and turns it in to a ninja
description that gets pretty-printed.  The GET-INSTALL-PATH is only
@echo commands and is parsed by development/testrunner/runtest.py, so
it fails to parse the pretty-printed first test.

Add a dummy @echo to GET-INSTALL-PATH for kati to use as the
description, so the rest of the @echo commands are left unmodified.
