osl: Windows pipe converted from OSL_ASSERT to assert/SAL_WARNs
Explanation for each conversion:
- osl_acceptPipe()
- don't worry about an invalid oslPipe sent as function parameter, we
check for the error returned by ConnectNamedPipe(), and without a
valid pipe we just need to return nullptr
- warn if INVALID_HANDLE_VALUE for the file handle, should be handled by
ConnectNamedPipe()
- createPipeImpl() allocates and initializes memory for the
oslPipeImpl structure, if it can't do this then something has been
done wrongly
- osl_receivePipe()
- invalid pipe needs to assert because ResetEvent needs valid
pPipe->m_ReadEvent
- osl_sendPipe()
- invalid pipe needs to assert because ResetEvent needs valid
pPipe->m_ReadEvent
- osl_writePipe()
- really just a thin wrapper around osl_sendPipe()
- osl_readPipe()
- really just a thin wrapper around osl_receivePipe()
