vamp-plugin-sdk: Update to 2.8.0

Version 2.8, 2019-02-07 (maintenance and minor feature release)

  * When running in a 32-bit process within 64-bit Windows (WoW64),
    use the VAMP_PATH_32 environment variable instead of VAMP_PATH
    (hosts running in this context already use "Program Files (x86)"
    instead of Program Files)
  * Fix off-by-one rounding errors in frame-to-ns conversions. Unlike
    the other changes here which are invisible to plugin code, this
    change can lead to different results in the lowest significant
    figures from existing plugins if relinked against the newer code
  * Fix path environment variable character encoding handling on
    Windows
  * Fix theoretical possibility of integer overflow in RealTime
    constructor
  * Fix use of undefined behaviour in PluginRateExtractor

Version 2.7.1, 2017-03-06 (maintenance release)

  * Fix inclusion mechanism for FFTs which could cause a host
    application to crash in certain circumstances due to
    conflicting versions of C-linkage symbols

Version 2.7, 2017-02-24 (maintenance and minor feature release)

  * Add ability to PluginLoader to list plugins only in (or not in)
    certain library files
  * Fix fixed-sample-rate output timestamps in printout from the
    simple host, and add regression test script using test plugin
  * Switch the convenience FFT interface for plugin usage from the
    very slow reference implementation previously provided, to the
    somewhat faster KissFFT
  * Add a top-secret compiler flag to switch internal FFTs to single-
    precision only
  * Fix some small but long-standing memory leaks and minor bugs
