To import a new snapshot:

On Linux, get the latest tar, untar, and replace src/ with libxml2-X.Y.Z/.

Remove:
  src/doc/
  src/example/
  src/os400/
  src/python/
  src/result/
  src/test/
  src/vms/
  src/VxWorks/

Generate config.h, include/libxml/xmlversion.h, and xml2-config:

cd linux
../src/configure --without-iconv --with-icu --without-ftp --without-http
cd ..
Patch config.h to not define HAVE_RAND_R since we use this file on Android
and it does not have it.

On a Mac, do the same in the mac/ subdir for config.h and
include/libxml/xmlversion.h and copy those to the Linux box in mac/

On a Windows box:
cd libxml2-2.9.2\win32
cscript //E:jscript configure.js compiler=msvc iconv=no icu=yes ftp=no http=no
Then copy config.h and include/libxml/xmlversion.h to win32/ on Linux.


Update BUILD.gn and libxml.gyp as necessary to add/remove files, etc.
