In order to allow users to manually populate the download directory with valid content change the assumption that missing the donestamp file means unfetched content. This allows users to populate the download dir without needing to create dummy .done files such that a user does not need a PREMIRROR when using BB_NO_NETWORK to provide valid content files in the download directory. To ensure the correct result this change also fails first if the localpath does not exist. This prevents further parts of the function attempting to calculating the checksum on non-existent files. This also fixes some edge conditions around where if the donestamp exists but the localpath does not it returns, and did not remove the donestamp. Also added test cases to cover this use case and additional use cases where for example the fetcher does not support checksums.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
