journal: add dst_allocated_size parameter for compress_blob
compress_blob took src, src_size, dst and *dst_size, but dst_size wasn't used as an input parameter with the size of dst, but only as an output parameter. dst was implicitly assumed to be at least src_size-1. This code wasn't *wrong*, because the only real caller in journal-file.c got it right. But it was misleading, and the tests in test-compress.c got it wrong, and worked only because the output buffer happened to be the same size as input buffer. So add a seperate dst_allocated_size parameter to make it explicit what the size of the buffer is, and to allow test to proceed with different output buffer sizes.
