Improve performance of inline functions. * NEWS.8.md: Announce compatibility and performance improvements. * scripts/legacy/@inline/inline.m: Add new field "fh" to inline class which holds an anonymous function handle implementing the inline function. Rename member variable "numArgs" to "nargs" to get away from CamelCase. * scripts/legacy/@inline/feval.m: Re-use existing class member variable "fh" to execute function rather than creating it every time feval() is called. * scripts/legacy/@inline/nargin.m: Update to use class member variable "nargs" rather than "numArgs".

Summary of important user-visible changes for version 8 (yyyy-mm-dd):
---------------------------------------------------------------------

### General improvements

- Octave's libraries are now built using symbol visibility by default.
That means that less symbols are exported from these libraries.
Configure with `--disable-lib-visibility-flags` to export all symbols
(as in previous versions).

### Graphical User Interface


### Graphics backend


### Matlab compatibility

- `inline` functions now support all Matlab methods.  The performance
  of `inline` functions has also been improved.

- `sub2ind` now supports index values outside of the size specified by
  the subscripts.

- `cylinder` now accepts a scalar for the radius argument.

- `clock` now has an optional second output `ISDST` which indicates if
  Daylight Savings Time is in effect for the system's time zone.

### Alphabetical list of new functions added in Octave 8


### Deprecated functions, properties, and operators

The following functions and properties have been deprecated in Octave 8
and will be removed from Octave 10 (or whatever version is the second
major release after 8):

- Functions

  Function               | Replacement
  -----------------------|------------------
  `shift`                | `circshift`
  `sparse_auto_mutate`   | none (see below)

- The `sparse_auto_mutate` function no longer has any effect on Octave's
  behavior.  Previously, after calling `sparse_auto_mutate (true)`,
  Octave would automatically convert sparse matrices to full when a
  sparse matrix required more memory than simply using full matrix
  storage.  This setting was `false` by default for compatibility with
  Matlab.  Now you must manually convert to full storage when desired.

The following functions were deprecated in Octave 6 and have been removed
from Octave 8.

- Functions

  Function               | Replacement
  -----------------------|------------------
  `runtests`             | `oruntests`

- The environment variable used by `mkoctfile` for linker flags is now
  `LDFLAGS` rather than `LFLAGS`.  `LFLAGS` was deprecated in Octave 6,
  and will be removed in a future version of Octave.
