Add few docs and implementation of strcpy and strcat. Summary: This patch illustrates some of the features like modularity we want in the new libc.

Add implementations of POSIX mmap and munmap functions. Summary: A set of of linux x86_64 internal syscall helpers have also been added. This change does not try to be perfect with respect to OS and machine abstractions. A TODO note has been added at places where such abstractions would help and make the arrangement scalable and cleaner. Addressing the TODOs and building such abstractions is not in the scope of this change. It is hoped that follow up changes cleaning up the problem areas and addressing the TODOs will better illustrate the need for the changes. This change also does not try to imitate mmap and munmap implementations of other libcs. The idea here is to put in the bare minimum required to obtain a working mmap and munmap, and then add the rest of the functionality on an as needed basis.

Initial commit of mktime. This introduces mktime to LLVM libc, based on C99/C2X/Single Unix Spec. Co-authored-by: Jeff Bailey <jeffbailey@google.com> This change doesn't handle TIMEZONE, tm_isdst and leap seconds. It returns -1 for invalid dates. I have verified the return results for all the possible dates with glibc's mktime. TODO: + Handle leap seconds. + Handle out of range time and date values that don't overflow or underflow. + Implement the following suggestion Siva - As we start accumulating the seconds, we should be able to check if the next amount of seconds to be added can lead to an overflow. If it does, return the overflow value. If not keep accumulating. The benefit is that, we don't have to validate every input, and also do not need the special cases for sizeof(time_t) == 4. + Handle timezone and update of tm_isdst Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D91551

Add implementations of POSIX mmap and munmap functions. Summary: A set of of linux x86_64 internal syscall helpers have also been added. This change does not try to be perfect with respect to OS and machine abstractions. A TODO note has been added at places where such abstractions would help and make the arrangement scalable and cleaner. Addressing the TODOs and building such abstractions is not in the scope of this change. It is hoped that follow up changes cleaning up the problem areas and addressing the TODOs will better illustrate the need for the changes. This change also does not try to imitate mmap and munmap implementations of other libcs. The idea here is to put in the bare minimum required to obtain a working mmap and munmap, and then add the rest of the functionality on an as needed basis.

[libc] Add fully-qualified target names. Only targets setup by the special LLVM libc rules now have fully qualified names. The naming style is similar to fully qualified names in Python. Reviewers: abrachet, PaulkaToast, phosek Differential Revision: https://reviews.llvm.org/D77340
