e73a7ab224 net/softnic: promote manage API
This API was introduced in 18.08, therefore removing
experimental tag to promote it to stable state.

18218713bf enforce experimental tag at beginning of declarations
Putting a '__attribute__((deprecated))' in the middle of a function
prototype does not result in the expected result with gcc (while clang
is fine with this syntax).

$ cat deprecated.c
void * __attribute__((deprecated)) incorrect() { return 0; }
__attribute__((deprecated)) void *correct(void) { return 0; }
int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
$ gcc -o deprecated.o -c deprecated.c
deprecated.c: In function ‘main’:
deprecated.c:3:1: warning: ‘correct’ is deprecated (declared at
deprecated.c:2) [-Wdeprecated-declarations]
 int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
 ^

Move the tag on a separate line and make it the first thing of function
prototypes.
This is not perfect but we will trust reviewers to catch the other not
so easy to detect patterns.

sed -i \
     -e '/^\([^#].*\)\?__rte_experimental */{' \
     -e 's//\1/; s/ *$//; i\' \
     -e __rte_experimental \
     -e '/^$/d}' \
     $(git grep -l __rte_experimental -- '*.h')

Special mention for rte_mbuf_data_addr_default():

There is either a bug or a (not yet understood) issue with gcc.
gcc won't drop this inline when unused and rte_mbuf_data_addr_default()
calls rte_mbuf_buf_addr() which itself is experimental.
This results in a build warning when not accepting experimental apis
from sources just including rte_mbuf.h.

For this specific case, we hide the call to rte_mbuf_buf_addr() under
the ALLOW_EXPERIMENTAL_API flag.

a958a5c07f net/softnic: support service cores
Add support to run the Soft NIC device on service cores, based on the
value of the sc parameter:

0: The current Soft NIC device is run explicitly by the application. The
   firmware creates one or several pipelines for this dev and maps them
   to CPU cores that should not be service cores. The app is required to
   call rte_pmd_softnic_run() to make this dev work.

1 (default): The current device is run on the service cores transparently
   to the app. The firmware creates one or several pipelines for this dev
   current device and maps them to CPU cores that should be service cores.
   Each of these service cores is calling rte_pmd_softnic_run()
   in order to make this dev work with no app intervention.
