[PATCH v3 00/11] msvc integration changes

[Tyler Retzlaff]

In accordance with draft plan
http://mails.dpdk.org/archives/web/2023-February/002023.html
introduces conditionally compiled code to enable building with MSVC that
_does not_ require C99/C11 meaning it can be integrated now.

This series covers minimal changes for item #2 in draft plan for EAL
dependencies kvargs, telemetry and consumed EAL public headers.

Note if any patch in the series requires in-depth discussion I'll
detach it from this series for separate submission & more focused
discussion so it doesn't block the entire series.


v3:
  * v3 does not group together conditional blocks when experimented
    with it didn't reduce conditionals enough to make it worth
    while. once msvc tests are at a running point i suggest
    a narrow targeted discussion about code organization without
    blocking this series
  * v3 does not attempt to refactor to use intrinsics for non-msvc
    compilers. again this should be done as a separate follow-up
    series later if desired
  * fix expansion of likely and unlikely macros
  * remove unnecessary define for rte_smp_{r,w}mb it is sufficient
    for these to be compiler barriers on x86
  * add a new patch to use __cpuid and __cpuidex intrinsics when
    building with msvc
  * add a new patch to use _umonitor, _umwait and _tpause intrinsics
    when building with msvc
v2:
  * use _mm_{l,s,m}fence intrinsics for rte_smp_{r,w,}mb macros
    are intended to be memory barriers not compiler barriers on
    x86_64.

Tyler Retzlaff (11):
  eal: use rdtsc intrinsic when compiling with msvc
  eal: use rtm and xtest intrinsics when compiling with msvc
  eal: use barrier intrinsics when compiling with msvc
  eal: use cpuid and cpuidex intrinsics
  eal: use umonitor umwait and tpause intrinsics
  eal: typedef cpu flag enum as int for msvc
  eal: hide GCC extension based alignment markers
  eal: expand most macros to empty when using msvc
  eal: exclude exposure of rte atomic APIs for MSVC builds
  telemetry: disable json print formatting with msvc
  telemetry: avoid expanding versioned symbol macros on msvc
