[jdk8u-dev] RFR: 8315506: C99 compatibility issue in LinuxNativeDispatcher [v2]

[Florian Weimer]

> The `Java_sun_nio_fs_LinuxNativeDispatcher_getlinelen` function calls the `free` function without including `<stdlib.h>`. This results in an implicit function declarations, and some compilers no longer support that by default, leading to a build failure.
> 
> Per the comment in the file, this function was introduced in the backport from jdk11, so this bug is specific to jdk8u.
> 
> Patch originally submitted by @djdelorie as openjdk/jdk8u#42.
