Summary:
Previously it was required to provide SDKROOT during configure on Mojave
hosts to `make` the project which in scripts was messing up local clang
and somewhat error-prone. Instead we could use xcrun to find required SDK
paths automatically.

Summary:
The model for `getcwd` assumes the first argument should be non-null when in fact a NULL pointer is legitimate and results in allocation:
> As an extension to the POSIX.1-2001 standard, glibc's getcwd() allocates the buffer dynamically using mal‐
> loc(3) if buf is NULL. In this case, the allocated buffer has the length size unless size is zero, when buf
> is allocated as big as necessary. The caller should free(3) the returned buffer.
I suggest this glibc extension be used for the getcwd model to reduce false positives.

Add support for Makefiles to the copyright linter. Makefiles are a bit
different than shell because they should start with the copyright notice
straight away (whereas shell starts with the #! stuff).

Summary:
It can be useful when debugging infer or the Makefiles themselves to see what
`make` is doing. Instead of editing Makefiles to remove `@` now you can `make
VERBOSE=1`.
This is just `git ls-files | grep -e Makefile -e '.*\.make' | xargs sed -e 's/^\t@/\t$(QUIET)/' -i`, and adding the definition of `QUIET` to Makefile.config.

Summary:
Given that mangling now respects `extern "C" {}` declarations, pnames of C function will have no mangling and we don't need to discard mangled part from procname.
Move `malloc` detection to `get_builtin_pname_opt` function (together with all others)

Summary:
Use Itanium mangling for C++ functions/methods instead of raw type name. This is a step towards removing expensive `ti_raw` field from `type_info`.
For virtual methods, use mangled name of the method from base class in order for dynamic dispatch to work.

Summary:
When analyzing C model in C++, we were seeing some SKIP function triggered by generated constructors/operators= for C structs.
In C they weren't present, but in C++ compiler generates them for us. To avoid this (and future) problems
with models, translate all functions that are needed when computing the model

Summary:
Array types where the length is not statically known were represented
using fresh variables. This diff:
- Makes array type length optional, reducing the amount of work needed
for renaming, substitution, and normalization.
- Revises uses of array length so that the length component of a
Tarray type represents only the statically determined constant
length of an array type, and the length component of a Sizeof
expression represents the dynamically determined length of an array
value.
- Restricts the type of static lengths from a general expression
(Sil.exp) to an integer (Sil.Int.t), enforcing that static types are
constant. This in particular ensures that types contain no
variables, and so are invariant under operations such as renaming
and substitution.
- Removes the type substitution and renaming functions typ_sub,
typ_normalize, and typ_captured_ren. Now that array type lengths
are constant integers, all of these functions are the identity.

Summary: @publicThe first argument of builtin calls in C gets translated twice, which is bad if the argument is a side-effecting expression like a function call.
Test Plan: Attached test previously reported a memory leak because the translation introduces an extra call to malloc(), now reports nothing.
Summary:
@public
Remove setjmp that is causing problems in the models in linux.
Will investigate and add it again later.
Test Plan: All the models are now created. In particular strcpy, strdup and a few others in the beginning of the file.
