No failure when fn:transform() requests streaming and streaming not available

Description
The fn:transform() function has the opporunity to request an XSLT processor with support for particular optional features. If it requests a processor that supports streaming then the request should fail FOXT0001 if no streaming XSLT processor is available (for example, under Saxon-HE). Currently it is not failing, but rather falls back to non-streaming mode, which is not conformant.
Similar considerations apply when the request is for higher-order-function or dynamic-evaluation support.

We now fail the fn:transform call if a requested feature is not available because it requires PE/EE and/or a license key. For requests such as dynamic evaluation, schema awareness, and streaming, if the request is to have the feature OFF, we disable it in the target configuration when the target configuration would otherwise allow it.
The changes caused a regression for test fn-transform-71 which requests a non-schema-aware processor and then tries to do a schema-aware transformation. This is because setting SCHEMA_AWARE = false on the processor doesn't have the expected effect of disabling schema awareness - in fact, it is the default. The meaning of the flag is explained in CompilerInfo.setSchemaAware: "Say that the stylesheet must be compiled to be schema-aware, even if it contains no xsl:import-schema declarations." In the presence of xsl:import-schema, as in this test case, the flag is ignored.
So a request for is-schema-aware=false will be rejected if the processor is EE.
