Doychin Atanasov 37d63df227
Add support for the FUSE_BATCH_FORGET operation (#123) 
There are certain Kernel versions which do not send individual
Forget operations after they receive "not implemented" for Batch Forget.
One example is "5.4.0-110-generic" on Ubuntu 20.04. I am sure there are
plenty of others.

This leads to inode "leaks". Where reference counts are never decreased
and the inodes were left hanging around long after they are not needed
any more.

The best way to fix that was adding support for batch operations to the
lib. This way all users will be able to benefit from the batching
optimization.

Michael Stapelberg 1c9fe7bc84 remove memclr/memmove entirely now that they are unused 
This breaks with newer Go versions AFAICT, so it’s easier to just remove it entirely.

Vitaliy Filippov c818f6216b Implement vectored read support 
Read requests can now take vectored responses from the filesystem
implementation and send them to FUSE device via the writev() system call.

This allows file systems to send data without copying it into the
library-provided buffer if the data is already in memory.

InMessage is initialized with a storage allocated before reads (#110) 
Fixes #109. In #102, the storage of the InMessage gets allocated every
time it's being read, which is expensive and caused issues like
https://github.com/GoogleCloudPlatform/gcsfuse/issues/563. So, this
change moves the allocation to its own function, called only once when
the struct is initialized before the reads.

Michael Stapelberg 0630024b2b switch from assembly stubs to go:linkname comment 
The go:linkname way works with Go 1.17 (with regabi), too.

Upstream did this in 2015 in
0b8d583320

See also https://sitano.github.io/2016/04/28/golang-private/ for more background
about both techniques.
