[oe] [meta-networking][rocko][PATCH v3] civetweb: Add new recipe with git-based version

[Krzysztof Kozlowski]

Add recipe for CivetWeb: easy to use, powerful, C/C++ embeddable web
server with optional CGI, SSL and Lua support, under MIT license.

CivetWeb provides C and C++ libraries and a standalone server binary.

Choose specific post-v1.10 git revision b8148afe8fa4 which has a fixed
SSL support (depending on OpenSSL v1.0.2).

Signed-off-by: Krzysztof Kozlowski <krzk at kernel.org>

Changes since v2:
1. Bump to post-v1.10 git revision.
2. Add ssl package config.
3. Drop cgi, cpp and debug from default package config.

Changes since v1:
1. Use SRCREC as suggested by Khem Raj.
2. Drop nativesdk class.
3. Fix native build with patch.
4. Explicitly disable SSL (does not build at v1.10).
5. Disable ASAN (not applicable for native builds).

+Subject: [PATCH] Unittest: Fix missing librt and libm during native compilation
+
+civetweb looks for librt and libm in weird places and for native build
+this fails:
+
+    | ../third_party/lib/libcheck.a(check.c.o): In function `tcase_create':
+    | build/tmp/work/x86_64-linux/civetweb-native/1.10-r0/build/third_party/src/check-unit-test-framework/src/check.c:145: undefined reference to `floor'
+    | build/tmp/work/x86_64-linux/civetweb-native/1.10-r0/build/third_party/src/check-unit-test-framework/src/check.c:148: undefined reference to `floor'
+
+These are needed dependencies so try regular system linkage in such
+case.
