RFC tools lib traceevent: Rename pevent to tep for preparation for library

[
Resending as quilt mail threading was broken, but luckily was fixed by

Having libtraceevent turn into a proper library has long been asked for. I never had time to do it before. Luckily, Tzvetomir was able to spend the time to start the preparation. The first thing that needs to be done is to handle namespace collisions. "pevent" was the prefix I chose, but many people were displeased by it, as it didn't express what the functions were used for. After discussing with many people at many conferences I've come up with "tep", which means "Trace Event Parser". Please don't question this. The bikeshed has been painted and I'm not changing the color.

This series changes all the function names and data structures from the "pevent_" prefix to the "tep_" prefix. Note, it does not change the names of local variables or even parameters. "pevent" variables and parameters still exist. We can change those later, but for now, I want all global references to "pevent" to be "tep_" instead.

This is not complete. It is only one of many preparations to make libtraceevent into a legitimate library. There's other naming conventions that will be made. But for now, I would like to hear thoughts about this change before we proceed further.

Instead of doing one big update, Tzvetomir grouped changes together. I compiled each patch to make sure perf still builds without errors at each step. I only used my own configuration, thus there may be cases that perf might fail to build. Here's what I had:

Auto-detecting system features:

...                         dwarf: [ on  ]
...            dwarf_getlocations: [ on  ]
...                         glibc: [ on  ]
...                          gtk2: [ on  ]
...                      libaudit: [ OFF ]
...                        libbfd: [ on  ]
...                        libelf: [ on  ]

... libnuma: [ OFF ]
... numa_num_possible_cpus: [ OFF ]
... libperl: [ OFF ]
... libpython: [ on ]
... libslang: [ OFF ]
... libcrypto: [ on ]
... libunwind: [ OFF ]

...            libdw-dwarf-unwind: [ on  ]
...                          zlib: [ on  ]
...                          lzma: [ on  ]
...                     get_cpuid: [ on  ]
...                           bpf: [ on  ]

The above is the config I used for testing the build.
