Link against system bcc Previously, bpftrace was clone bcc from github at build time, building a version of bcc, then linking against the built bcc. This is a no-go for many packaging systems including Fedora, openSUSE, and the internal Facebook one. This patch requires bcc and bcc development headers be installed to build bpftrace and removes the build time downloading behavior. Also simplifies some of the header search logic. Test plan: ``` $ ./build/tests/bpftrace_test ... $ sudo make -C build runtime-tests ... $ cat ~/scratch/bpftrace/path.bt kprobe:vfs_open { printf("open path: %s\n", str(((path *)arg0)->dentry->d_name.name)); } $ sudo ./build/src/bpftrace ~/scratch/bpftrace/path.bt [sudo] password for dlxu: Attaching 1 probe... open path: stat open path: user-745673103.journal open path: user-1001.journal open path: user-745673103.journal open path: user-1001.journal open path: user-745673103.journal open path: user-1001.journal open path: iio:device0 open path: stat ...

`*-inl.h` files, or inline headers, are an implementation detail. Users of an interface that is backed by an inline header should not concern themselves with the details of implementation. This patch normalizes the interface.

Avoid crashing if mistakenly just '-d' or '-v' is used

Currently, if by mistake just '-v' or '-d' is used without any additional parameter (no filename nor -e 'program') bpftrace crashes: ./src/bpftrace -v terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid Aborted (core dumped) This commit fix this problem.

we were moving as far as constructor arg, but afterwards we were copying to member. this fixes that. https://stackoverflow.com/a/16725030/5257399

Previously get_arg_values was returning a vector of uint64_t values that could be passed directly to printf(3). For string values get_arg_values was returning a pointer to a char*. For some cases it was attempting to handle freeing the char* memory via a stack allocated std::vector. Unfortunately, this was stack allocated in get_arg_values so the char* data would get freed before it was used in the subsequent call to printf(). In other cases get_arg_values was not freeing char* values and was leaking memory (probe, stack, and ustack). get_arg_values() now returns a vector of objects of type IPrintable instead of uint64_t values. Each object has a method .value() that returns the uint64_t value usable by printf(). For strings this allows us to keep around the original std::string until after we've called printf(), so we don't need to strdup() anymore. Fixes #194
