MemoryTracking: fix logging of free() calls done where Curl_safefree is called Just internal stuff... Curl_safefree is now a macro defined in memdebug.h instead of a function prototyped in url.h and implemented in url.c, so inclusion of url.h is no longer required in order to simply use Curl_safefree. Provide definition of macro WHILE_FALSE in setup_once.h in order to allow other macros such as DEBUGF and DEBUGASSERT, and code using it, to compile without 'conditional expression is constant' warnings. The WHILE_FALSE stuff fixes 150+ MSVC compiler warnings.

free: instead of Curl_safefree() Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.

Modified curl_accept() to take a 'void *' in the 2nd argument instead of sockaddr *. This has the added benefit that source files that include memdebug.h doesn't have to know about "sockaddr".

build: fix circular header inclusion with other packages This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

Reinstate "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage". This reverts commit 7ed25cc, reinstating commit 8ec2cb5. As of 18-jul-2013 we still do have code in libcurl that makes use of these memory functions. Commit 8ec2cb5 comment still applies and is yet valid. These memory functions are solely used in Windows builds, so all related code is protected with '#ifdef WIN32' preprocessor conditional compilation directives. Specifically, wcsdup() _wcsdup() are used when building a Windows target with UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case when building a Windows UNICODE target with Windows native SSL/TLS support enabled. Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage of these is hidden behind _tcsdup() which is MS way of dealing with code that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS header files and those compatible from other compilers use this preprocessor conditional compilation directive in order to select at compilation time whether 'wide' or 'ansi' MS API functions are used. Without this code, Windows build targets with Windows native SSL/TLS support enabled and MemoryTracking support enabled misbehave in tracking memory usage, regardless of being a UNICODE enabled build or not.

Modified curl_accept() to take a 'void *' in the 2nd argument instead of sockaddr *. This has the added benefit that source files that include memdebug.h doesn't have to know about "sockaddr".

Since the NSS lib closes the socket the memory tracking system wrongly gets a false positive on a leaked socket, so this introduces a way to tell the system that the socket is indeed closed without explicitly closing it!

MemoryTracking: fix logging of free() calls done where Curl_safefree is called Just internal stuff... Curl_safefree is now a macro defined in memdebug.h instead of a function prototyped in url.h and implemented in url.c, so inclusion of url.h is no longer required in order to simply use Curl_safefree. Provide definition of macro WHILE_FALSE in setup_once.h in order to allow other macros such as DEBUGF and DEBUGASSERT, and code using it, to compile without 'conditional expression is constant' warnings. The WHILE_FALSE stuff fixes 150+ MSVC compiler warnings.

free: instead of Curl_safefree() Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.
