Import curl 7.43
This is a simple import of curl 7.43.
The only change from the official release is the fact that the
Android.mk was removed to avoid build error trying to parse it.

+# table for all known symbols for which version they were introduced.

+# It then scans the given source file to dig up all symbols starting with CURL.
+# Finally, it sorts the internal list of found symbols (using the version
+# number as sort key) and then it outputs the most recent version number and
+# the symbols from that version that are used.

+# Usage:
