core: rename FOO_BASE_NAME to FOO_BASENAME to avoid clashes

In current Buildroot, clashes occur between the variables _NAME and
_BASE_NAME for two packages called foo and foo-base, i.e.

Package foo:
FOO_NAME = foo
FOO_BASE_NAME = foo-1.2.3

Package foo-base:
FOO_BASE_NAME = foo-base
FOO_BASE_BASE_NAME = foo-base-4.5.6

where variable FOO_BASE_NAME is clashing between these two packages.
Specific cases where this clash is already existing are:
- alljoyn-base
- alljoyn-tcl-base
- perl-xml-sax-base

The problem is generic and can occur for a number of variables in Buildroot.
A non-exhaustive list:
    <pkg>_BASE and <pkg>_BASE_NAME
    <pkg>_BASE_NAME and <pkg>_RAW_BASE_NAME
    <pkg>_DIR and <pkg>_DL_DIR
    <pkg>_VERSION and <pkg>_DL_VERSION
    <pkg>_SOURCE and <pkg>_TARGET_SOURCE
    <pkg>_INSTALL_IMAGES and <pkg>_TARGET_INSTALL_IMAGES  (same for _STAGING and _TARGET)
    <pkg>_LICENSE_FILES and <pkg>_MANIFEST_LICENSE_FILES
    <pkg>_DEPENDENCIES and <pkg>_FINAL_DEPENDENCIES

One solution is to use another separator than '_' to separate the
package name from the rest of the variable name. For example, a double
underscore:
FOO__NAME
FOO__BASE_NAME
FOO_BASE__NAME
FOO_BASE__BASE_NAME

However, making that change for only this case means that the variable
naming is no longer consistent. And making the change for all variables has
a large impact, also on certain user scripts.

For now, keep it simple, and rename FOO_BASE_NAME into FOO_BASENAME, so that
the variables become:
FOO_NAME
FOO_BASENAME
FOO_BASE_NAME
FOO_BASE_BASENAME

For consistency, also adapt FOO_RAW_BASE_NAME. Since FOO_RAW_BASENAME would
still pose a conflict with a package called 'foo-raw', take the opportunity
to rename it into FOO_BASENAME_RAW instead, which does not pose a conflict
as we have no variable called FOO_RAW.
