Fix mmap / libaio deadlock Calling uiomove() in mappedread() under the page lock can result in a deadlock if the user space page needs to be faulted in. Resolve the issue by dropping the page lock before the uiomove(). The inode range lock protects against concurrent updates via zfs_read() and zfs_write().

Clean up lib dependencies libzutil is currently statically linked into libzfs, libzfs_core and libzpool. Avoid the unnecessary duplication by removing it from libzfs and libzpool, and adding libzfs_core to libzpool. Remove a few unnecessary dependencies: - libuutil from libzfs_core - libtirpc from libspl - keep only libcrypto in libzfs, as we don't use any functions from libssl - librt is only used for clock_gettime, however on modern systems that's in libc rather than librt. Add a configure check to see if we actually need librt - libdl from raidz_test Add a few missing dependencies: - zlib to libefi and libzfs - libuuid to zpool, and libuuid and libudev to zed - libnvpair uses assertions, so add assert.c to provide aok and libspl_assertf Sort the LDADD for programs so that libraries that satisfy dependencies come at the end rather than the beginning of the linker command line. Revamp the configure tests for libaries to use FIND_SYSTEM_LIBRARY instead. This can take advantage of pkg-config, and it also avoids polluting LIBS. List all the required dependencies in the pkgconfig files, and move the one for libzfs_core into the latter's directory. Install pkgconfig files in $(libdir)/pkgconfig on linux and $(prefix)/libdata/pkgconfig on FreeBSD, instead of /usr/share/pkgconfig, as the more correct location for library .pc files.
