  1. meson: Add generated header stamps 

    Otherwise build commands become too long and this has visible effect on
creation time of meson build files.

  2. meson: Add postgresql-extension.pc for building extension libraries 

    This should work with several other buildsystems.

  3. meson: Test building extensions by using postgresql-extension.pc 

    The 'test_meson_extensions' pyton wrapper is added to run these tests.
It compiles and builds extensions at
${build}/testrun/meson_extensions/${extension_name} path.

The tests for building amcheck, auth_delay and postgres_fdw extensions
are added. These are also examples of how to build extensions by using
postgresql-extension.pc.

  5. meson: Add architecture for LLVM bitcode emission 

    This commit adds suport for bitcode emission for both normal and
generated source files (processed by bison, flex, etc). These bitcode
files are installed into $pkglibdir/bitcode/ directory if the LLVM is
found.

New variable `bitcode_modules` is introduced to generate bitcode files.
All required information is gathered in this variable. Then, this
variable is processed by the main meson LLVM bitcode emission scripts:
src/backend/jit/llvm/bitcode/meson.build -> src/tools/irlink.

An example of a possible structure of bitcode_modules is:
```
bitcode_modules = [
  {
    'name': '...',
    'target': ...,
    'srcfiles': [
      '...',
      '...',
    ],
    'additional_flags': [
      '-I...',
      '-I...',
    ],
    'gen_srcfiles': [
      {
        'srcfiles': [
          <custom_target for ...>,
          <custom_target for ...>,
        ],
        'additional_flags': [
          '-I...',
          '-I...',
        ]
      }
    ]
  }
]
```

  6. meson: Add LLVM bitcode emissions for contrib libraries 

    The libraries which the bitcode files will be generated in are selected
manually.

  7. meson: Add LLVM bitcode emission for backend sources 

    Since generated backend sources may have their own compilation flags and
must also be included in the postgres.index.bc, the way to make it work
with current code was to create a new variable, called
`bc_generated_backend_sources`, which is a list of dictionaries, each
one having an optional 'additional_flags' and a `srclist` pointing to
the list of custom_target generated sources.

An example of a possible structure of bitcode_modules which is processed
by the main meson llvm bitcode emission file
src/backend/jit/llvm/bitcode/meson.build:
```
bitcode_modules = [
  {
    'name': 'postgres',
    'target': postgres_lib,
    'src_file': backend_sources,
    'gen_srcfiles': [
      {
        'additional_flags': [
          '-I/path/postgresl/src/backend/parser',
          '-I/path/postgresl/build/src/backend/parser',
        ],
        'srcfiles': [
                <custom_target for scan.c>,
                <custom_target for gram.c>
        ]
      }
    ]
  }
]
```

  8. [CF 5671] v6 - Produce LLVM bitcode files on meson builds 

    This branch was automatically generated by a robot using patches from an
email thread registered at:

The branch will be overwritten each time a new patch version is posted to
the thread, and also periodically to check for bitrot caused by changes
