Currently io-cache invalidate pages falling in the range of write. But
instead it can update pages with same data so that reads can make use
of the cache.

Removed all references to dict_t xdata_from_req which is
allocated but not used anywhere. It is also not cleaned up
and hence causes a memory leak.

When using list_for_each_entry(_safe) functions, care needs
to be taken that the list passed in are not empty, as these
functions are not empty list safe.

clag scan reported various points where this this pattern
could be caught, and this patch fixes the same.

Additionally the following changes are present in this patch,
- Added an explicit op_ret setting in error case in the
macro MAKE_INODE_HANDLE to address another clang issue reported
- Minor refactoring of some functions in quota code, to address
possible allocation failures in certain functions (which in turn
cause possible empty lists to be passed around)

symlink-cache was written as an experiment to reduce the load
on 'build' systems, which keep doing symlink resolution to get
the proper header files. But since last 6+ years, there was no
way to add it to the volfile using gluster cli, and hence was
not supported anymore. As it is not maintained, and as announced
on [1], we are planning to remove it from the build system.

Rename the identifiers, bit-rot-server to bit-rot in bit-rot.c & write-ahead to
write-behind in write-behind.c to ensure GD2 understands the options

stats from prefetched dentries should be invalidated only if the
files pointed to those dentries were written in the window of
prefetching. Otherwise its safe to use these stats.

Since glusterd2 don't maintain the xlator option details in code, it
directly reads the xlators options table from `*.so` files. To support
enable and disable of xlator new option added to the option table with
the name same as xlator name itself.

This change will not affect the functionality with glusterd1.
