9b84de4b0a hsavmcore: fix compiler warnings 
Compiling against fuse3 shows 'incompatible pointer type' warnings due
to the additional function arguments in the new API.

Therefore, adjust the declarations of vmcore_fuse_getattr() and
vmcore_fuse_readdir() to match.

e679a88d88 Switch from fuse2 to fuse3 
Fuse 3.0.0 was released in December 2016. The last maintenance release
from the 2.9 branch was in January 2019, and users are encouraged to
transition to the actively developed 3.x branch.
https://github.com/libfuse/libfuse/releases/tag/fuse-2.9.9

Therefore, adapt cmsfs-fuse, hmcdrvfs, hsavmcore, zdsfs and zdump to
the new API, and adapt associated Makefiles to link the new library.

8c9cc6e12a s390-tools: add hsavmcore utility 
hsavmcore is designed to make the dump process with kdump more efficient.
With hsavmcore, the HSA memory that contains a part of the production
kernel's memory can be released early in the process. Depending on the size
of the production kernel's memory, writing the dump to persistent storage
can be time consuming and prevent the HSA memory from being reused
by other LPARs.
