[libvirt] [PATCH] domain: add limit description of parameter 'size' for blockPeek and memoryPeek

From: Chen Hanxiao <chenhanxiao(a)gmail.com&gt; We had 'size' limits for virDomainMemoryPeek and virDomainBlockPeek by macro REMOTE_DOMAIN_BLOCK_PEEK_BUFFER_MAX and REMOTE_DOMAIN_MEMORY_PEEK_BUFFER_MAX. The descriptions of the two functions only emphasized RPC buffer size.
