* APR_DECLARE_STATIC and APU_DECLARE_STATIC gets already defined in APR.cmake
* Move both _CRT_SECURE_NO_WARNINGS and _WINSOCK_DEPRECATED_NO_WARNINGS definitions to 00-Common.cmake
* Always define WIN32_LEAN_AND_MEAN and include subset of Windows API by default
* Remove llwin32headerslean.h and remove unnecessary WIN32_LEAN_AND_MEAN definition handling in llwin32headers.h
* Clean up includes of Windows API headers
* Get rid of workaround to link against IPHLPAPI.lib in lluuid.cpp - this seems to have been an issue in the past that has been fixed
In llpreprocessor.h, consider the case of clang on Windows: #define
LL_WCHAR_T_NATIVE there as well as for the Microsoft compiler with /Zc:wchar_t
switch.
In stdtypes.h, inject a LLWCHAR_IS_WCHAR_T symbol to allow the preprocessor to
make decisions about when the types are identical.
llstring.h's conversion logic deals with three types of wide strings
(LLWString, std::wstring and utf16string) based on three types of wide char
(llwchar, wchar_t and U16, respectively). Sometimes they're three distinct
types, sometimes wchar_t is identical to llwchar and sometimes wchar_t is
identical to U16. Rationalize the three cases using ll_convert_u16_alias() and
new ll_convert_wstr_alias() macros.
stringize.h was directly calling wstring_to_utf8str() and utf8str_to_wstring(),
which was producing errors with VS 2019 clang since there isn't actually a
wstring_to_utf8str(std::wstring) overload. Use ll_convert<std::string>()
instead, since that redirects to the relevant ll_convert_wide_to_string()
function. (And now you see why we've been trying to migrate to the uniform
ll_convert<target>() wrapper!) Similarly, call ll_convert<std::wstring>()
instead of a two-step conversion from utf8str_to_wstring(), producing LLWString,
then a character-by-character copy from LLWString to std::wstring. That
isn't even correct: on Windows, we should be encoding from UTF32 to UTF16.
Add ll_convert<TO, FROM> template, used as (e.g.):
ll_convert<std::string>(value_of_some_other_string_type);
There is no generic template implementation -- the template exists solely to
provide generic aliases for a bewildering family of llstring.h string-
conversion functions with highly-specific names. There's a generic
implementation, though, for the degenerate case where FROM and TO are
identical.
Add ll_convert<> specialization aliases for most of the string-conversion
functions declared in llstring.h, including the Windows-specific ones
involving llutf16string and std::wstring.
Add a mini-lecture in llstring.h about appropriate use of string types on
Windows.
Add LL_WCHAR_T_NATIVE llpreprocessor.h macro so we can detect whether to
provide separate conversions for llutf16string and std::wstring, or whether
those would collide because the types are identical.
Add inline ll_convert_wide_to_string(const std::wstring&) overloads so caller
isn't required to call arg.c_str(), which naturally permits an ll_convert
alias.
Add ll_convert_wide_to_wstring(), ll_convert_wstring_to_wide() as placeholders
for converting between Windows std::wstring and Linden LLWString, with
corresponding ll_convert aliases. We don't yet have library code to perform
such conversions officially; for now, just copy characters.
Add LLStringUtil::getenv(key) and getoptenv(key) functions. The latter returns
boost::optional<string_type> in case the caller needs to detect absence of a
given environment variable rather than simply accepting a default value.
Naturally getenv(), which accepts a default, is implemented using getoptenv().
getoptenv(), in turn, is implemented using an underlying llstring_getoptenv().
On Windows, llstring_getoptenv() returns boost::optional<std::wstring> (based
on GetEnvironmentVariableW()), whereas elsewhere, llstring_getoptenv() returns
boost::optional<std::string> (based on classic Posix getenv()).
The beauty of generic ll_convert is that the portable LLStringUtilBase<T>::
getoptenv() template can call the platform-specific llstring_getoptenv() and
transparently perform whatever conversion is necessary to return the desired
string_type.
Add windows_message<T>(error) template, with an overload that implicitly calls
GetLastError(). We provide a single concrete windows_message<std::wstring>()
implementation because that's what we get from Windows FormatMessageW() --
everything else is a generic conversion to the desired target string type.
This obviates llprocess.cpp's previous WindowsErrorString() implementation --
reimplement using windows_message<std::string>().
These are mostly things that were in fact erroneous, but accepted by older
compilers.
This changeset has not yet been built with Visual Studio 2013 or Linux gcc,
even with -std=c++11.
This changeset has not been built *without* -std=c++11. It should be used in
conjunction with a corresponding change to LL_BUILD_DARWIN_BASE_SWITCHES in
viewer-build-variables/variables.
This is a work in progress. We do not assert that this changeset completes the
work needed to turn on -std=c++11, even on the Mac.
Also define LL_LIKELY/LL_UNLIKELY with a warning about its micro-optimizey nature, and use it to annotate llasserts (i.e. make llassert() lower-overhead and thus more attractive, even in inner-ish loops.)

The problem arose because we were setting LL_COMMON_BUILD in
llcommon/CMakeLists.txt, not only for the library build itself but also for
its LL_ADD_INTEGRATION_TEST tests. This told all the headers compiled into the
INTEGRATION_TEST_lllazy executable that the executable was providing all the
llcommon symbols, rather than importing them.
The solution is to switch to the llcommon_EXPORTS symbol automagically defined
by CMake when building the llcommon shared library itself.
Ok, finally got this to a point where it doesn't break the build and I can check
in. llcommon can be built as a shared library (disabled but can be enabled with
cmake cache var LLCOMMON_LINK_SHARED.
