Move include/rebar.hrl to src/rebar.hrl

ct fixes

Add REBAR to environment before executing hooks

Some optimisation/refactoring using stdlib's functions

Add qualified name tests specification (see #118)

Fix #176

Add support for the Perforce VCS client via the "p4" tool

* Corrected regexp: `[x|y]` -> `[xy]`.
* Used an re:replace/4 option instead of multiple IOlist functions.

Namespaced types: fix build for 17.0

We use namespaced_types option to choose between dict() and dict:dict() types.

REBAR will be set to the rebar binary which was executed and runs the
builds. Enables the use of the same binary for rebar invocations as
part of a pre or post hook like so:

    ${REBAR} escriptize

erlc: replace if expression with case of

Motivated by the bug fix in 2c4d7d1.

erlc: fix typo in update_erlcinfo/3 clause

suggested by @tuncer

noted by @tuncer

When trying to skip spec files under deps/ directory,
ignore "deps" component which is also included in Cwd.
For example, "/home/deps/src/myapp/test/cover.spec"
contains "deps" component but should not be skipped if
Cwd is "/home/deps/src/myapp/".

Extend CONTRIBUTING.md with regards to tests and credit.

Augment 'tests' option of 'rebar eunit' command with ability to specify
tests to run using module-qualified names. This change also forced me
to change the way modules for coverage and for testing itself are
selected - module-qualified tests specifications are now taken into
consideration. Extend tests to cover new functionality. Update
dialyzer_reference accordingly.

Error 'Command not found' when sname is used

improve output when using `rebar shell`

When a node is configured with -sname the REMSH_NAME_PART argument should be defined with using command 'hostname' but error occurs due extra space

attempt to emulate the behavior of
`erl -pa ebin -pa deps/*/ebin`

fix error messages and formatting issues of `rebar shell` by
shutting down and restarting the user subsystem in a mode more
hospitable to the shell than the simple user started when run
as an escript. emulate `error_logger` behaviour when the shell
is run via `erl`

add documentation of the shell command

limitations:

the erlang interrupt handler is not enabled when running as an
escript and there is no interface to re-enable it via erlang code.
this means `ctrl-c` will immediately exit the running process
unlike when running the shell via `erl`. `ctrl-g` is, however,
unaffected

the user subsystem is killed and restarted but not supervised. if
your code somehow relies on the user subsystem crashing and
restarting `rebar shell` may interfere with it's operation

rebar.hrl is only meant to be used by src/*.

Slim release support

Make sure that eunit/qc_compile_opts works

Document skip_apps=, apps=, and require_*_vsn

rebar.app: remove superfluous quoting

Use lowercase for Windows drive name to resolve issue #250

Extra commits for #129

base_dir() returns already filename:absname()'ed path.

On windows, bootstrap.bat failed with next error.
Command 'escriptize' not understood or not applicable

This happens because the drive name in path got from rebar_utils:get_cwd() and base_dir(Config) are different case.
Made the drive name the same lowercase using filename:absname().

file_utils: properly report errors (fix #95)

Update THANKS

Fix #267 (code path regression)

Since the introduction of -r/--recursive, deps were not properly added
to the code path when running ct, eunit, etc.

To fix that, pass a flag down to process_dir1 and conditionalize
execution of the command. This moves the decision into process_dir1
where we can decide to invoke preprocess/2 and postprocess/2 but not
execute the command.

Without this fix, you'd have to, for example, invoke 'rebar -r ct
skip_deps=true', if you wanted to run base_dir's ct suites with deps on
the code path (while skipping all non-base_dir ct suites).

So, with this patch applied, if you run
$ rebar ct
deps will be on the code path, and only base_dir's ct suites will be
tested.

If you want to test ct suites in base_dir and sub_dirs, you have to run
$ rebar -r ct skip_deps=true

If you want to test ct suites in all dirs, you have to run
$ rebar -r ct

The fix is not specific to ct and applies to all commands.

To be able to add inttest/code_path_no_recurse/deps, I had to fix
.gitignore. While at it, I've updated and fixed all entries.

* Fix arg order:
  The order of arguments got inconsistent over time. To fix that, use
  the same consistent order in all functions.

* Avoid one erlang:'++'/2 call in process_dir/6.

* Avoid lists:prefix/2 and atom_to_list/1 calls:
  We can easily avoid 2 lists:prefix/2 calls and one atom_to_list/1 call
  in execute/5 by passing in whether the command is a hook or not. The
  resulting code is simpler and easier to read.

Fix 'rebar help clean' function_clause error

Missing info(help, clean) in rebar_qc.erl.
