Björn Svensson c4dfb94e98 Use GNUC atomics from GCC 4.9 
GCC began to offer full support for the C11 standard starting with version 4.9,
including support for the _Atomic keyword.

https://gcc.gnu.org/gcc-4.9/changes.html

Björn Svensson 486200e57f Fix issue in Freebsd when building with GCC 14.1.0 
Since GCC 14 now implements `__has_extension()` the build started to use
Clang atomics, i.e. the `__c11_*` APIs only provided by Clang.

Fix build to use GNUC atomics and include the upstream patch:
  https://reviews.freebsd.org/D16585
which enables C11 atomics when building with GCC >= 4.7.

fengbojiang 021aaded2c Support zero copy while call `ff_write`, you can enable it by modify ‘FF_ZC_SEND=1' in `lib/Makefile`. 
`FF_ZC_SEND` is same as `FF_USE_PAGE_ARRAY`, it will improve performance slightly in some scenarios, need to be tested in combination with real applications.

You can enable both compilation options at the same time or separately.
