Aaron Ballman 527a420550 Add a new check, cert-env33-c, that diagnoses uses of system(), popen(), and _popen() to execute a command processor. This check corresponds to the CERT secure coding rule: https://www.securecoding.cert.org/confluence/pages/viewpage.action?pageId=2130132

Aaron Ballman a6ab2efed2 Renaming CERT documentation files to use the CERT rule identifiers. This is for consistency with other checkers, where the documentation file name matches the checker name. NFC of the checkers.

Aaron Ballman 43aef4cb9b Add a new checker, cert-err58-cpp, that checks for static or thread_local objects that use a throwing constructor. 
This check corresponds to the CERT secure coding rule: https://www.securecoding.cert.org/confluence/display/cplusplus/ERR58-CPP.+Constructors+of+objects+with+static+or+thread+storage+duration+must+not+throw+exceptions

Aaron Ballman f71c9661df Test to ensure the function does not have an unresolved or unevaluated exception specification before testing whether the function throws or not. Fixes PR25574.

Aaron Ballman 5a786ddf4c Add a new clang-tidy checker that flags throw expressions whose thrown type is not nothrow copy constructible. While the compiler is free to elide copy constructor calls in some cases, it is under no obligation to do so, which makes the code a portability concern as well as a security concern. 
This checker corresponds to the CERT secure coding rule: https://www.securecoding.cert.org/confluence/display/cplusplus/ERR60-CPP.+Exception+objects+must+be+nothrow+copy+constructible

Aaron Ballman e4b1765a0f Adding a checker (cert-err52-cpp) that detects use of setjmp or longjmp in C++ code. Corresponds to the CERT C++ secure coding rule: https://www.securecoding.cert.org/confluence/pages/viewpage.action?pageId=1834

Aaron Ballman ea2f90c96b Adding a new clang-tidy module to house CERT-specific checkers, and map existing checkers to CERT secure coding rules and recommendations for both C (https://www.securecoding.cert.org/confluence/display/c/SEI+CERT+C+Coding+Standard) and C++ (https://www.securecoding.cert.org/confluence/pages/viewpage.action?pageId=637).
