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.

BUG: 22347561

+## Makefile for building libcurl.a with MingW (GCC-3.2 or later)
+## and optionally OpenSSL (1.0.2a), libssh2 (1.5), zlib (1.2.8), librtmp (2.4)
 ##
-## Usage:
-## mingw32-make -f Makefile.m32 [SSL=1] [SSH2=1] [ZLIB=1] [IDN=1] [SSPI=1] [IPV6=1] [LDAPS=1] [RTMP=1] [DYN=1]
+## Usage:   mingw32-make -f Makefile.m32 CFG=-feature1[-feature2][-feature3][...]
+## Example: mingw32-make -f Makefile.m32 CFG=-zlib-ssl-sspi-winidn
 ##
 ## Hint: you can also set environment vars to control the build, f.e.:
-## set ZLIB_PATH=c:/zlib-1.2.5
+## set ZLIB_PATH=c:/zlib-1.2.8
 ## set ZLIB=1
