Subject: Cleanup: apply `include-what-you-use` guideline for `uint*_t`
X-Git-Tag: v2.13.0-rc1~547
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=fb31eb73d8a4a6d9784ed5c335b7fa3b9684108c;p=lttng-ust.git

Cleanup: apply `include-what-you-use` guideline for `uint*_t`

I saw that some files use `uint*_t` types but there are not including a
header for it. The `uint*_t` types is defined by the following header:
  <stdint.h>

So, to follow the best practice of including what is used in a file, I
added `#include <stdint.h>` in files using `uint*_t`.
